Photo sensitive burn.

I"m stumped,

Here's my thread, everything was good till last friday. :(

http://boards.cannabis.com/grow-log/...irst-grow.html






What is your experience level? (first timer, novice, experienced...)= No0b

Your Equipment:
.1) Type and wattage of lights. (MH, HPS, CFL's, tube fluorescents, LED's) = 2 50 watt incandescent "reflector" style bulbs and one 18" T8 fluorescent plant/aquarium, and the 60 watt soft white that is in the ceiling fixture.
.2) Distance from tops?= 18" on the tube, about 36" on the reflector bulbs, about 5 foot to the ceiling light.
.3) Reflector type? (cool tube set-up, bat wing, enclosed reflector, bare bulb...) =bare bulbs and mylar on walls
.4) Is there a consistent fresh air supply?= no, other than leaks in the current "tent" (4.5x6.5 room under construction, one wall is black plastic tarp, the other 3 are drywall, there is an actual locking door to enter.)
.5) Do you have an exhaust fan and a circulation fan?= Exhaust yes, but cant run it and keep temps above low 60's and humidity's above 30% Circulation, not really, but the humidifier is blowing over her,... it's something at least.
.6) What are the bulb wattages, kelvin ratings, and schedule?= Dont know kelvens, watts are 15 on the T8, 50 each on the reflector bulbs, and 60 on the ceiling bulb. stepped up to a 24-0 light schedule for healing her,... but am debating putting her back to 18-6 given the photo sensitivity of the burning. :wtf:

Your medium:
.7) Specific brand and type of soil, (coco, peat based soilless...) and anything you've added to it. (vermiculite, perlite, worm castings...)= Happy frog nothing added but water.
.8) Size of container.= 3 gallon.
.9) Did you use peat pucks (or similar) to root clones or germinate seedlings?= N/A

Your nutrients and water:
10) Source of water? (tap, bottled or filtered) What's it's ph before adjusting?= Tap, and I don't know.
11) Method of checking water ph. (ph pen, test strips, aquarium test kit...)= none
12) Method of adjusting water ph. (phosphoric acid, white vinegar, hydrated lime, PH Up...)= none
13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule. = none
14) How often are you watering between feedings, and how much per watering?= not feeding
15) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...)= none
16) Are your ph levels stable, or do they fluctuate?= dont know.
17) What is your ingoing water's ph? ...your runoff ph? = don't know
18) Do you foliar feed? If so, with what, how often, and at what time do you spray?= Feed no, but have been watering the leaves since i had to prune her back so much to stem off the die back,.... (see thread) as often as I can for frequency,... it seems to be helping keep the 1/2 dead leaves from drying out totally, and the new growth hasn't been burning until tonight.

Your growroom:
19) Indoors or outdoors?= Indoor
20) What size of closet, room or hut?= 4.5x6.5x7.5
21) What are the temps and humidity levels while lights are on? ...With lights off?=75-77*f and 44-60% (the 44% reading was during a time that the outside door was open,... mostly it's between 50-55%) currently on 24-0
22) Have you seen signs of insects in the growroom?= signs yes, maybe,... (see thread) I'm exposed to mites almost every day at work, from several sources, not to mention my own household garden.

Your strain:
23) What strain are you growing? (Indica dominate or Sativa dom?)= Grand Daddy Purple, Indica
24) From seeds or clones?= Clone
25) Is this an autoflower strain?=no
_



Please check the grow thread for more details, or ask here, My little girl will probably make it, but it's killing me to see her like this! :(

I want to see her healthy and happy again, please help!!!!! :o

Pics;

1- Friday night
2- Saturday morning
3/4 a couple pics from tonight.

I've posted this thread here because my plant had problems that I thought might have been resolved, but re-manifested tonight after adding reflective to the booth thus increasing the intensity of the lights.... then the burn returned.


please advise! :(

For starters, why would you ask for help, and have us do all the work thread-hopping? These are your plants, perhaps you should put-out the effort and explain here.
My comments are strictly from the info you provided here.

Inadequate light. Incandescents are no good for growing, nor are spot growlights. The throw out more heat than usable lumens. Fluoro tubes need to be within 2-4 inches to be effective. Ceiling light...?

There are minimum requirements to keeping cannabis happy and healthy. Fresh air supply (and the CO2 it contains) is a necessary component. Stagnant air chokes-off normal gas-air exchange.

Ingoing water ph is ultra important. Acceptable range for peat-based mediums is between 6.3 and 6.8ish. There are already ph buffers in the soil, but you still need to keep the water within range. A freshwater aquarium ph test kit runs around $7.00, but if on city water, you might be able to find out online. (Google)

When do plan on feeding 'em?

Can you keep 'em outside till you correct these issues?

The rest really doesn't matter. You have fatal flaws that need immediate addressing. If you seriously want to grow cannabis, you must have proper lighting or keep 'em outdoors. You must properly feed 'em, or they die. You should read your ass off and follow a couple of growlogs and see if you can gain the basics. When not following growlogs, you should read the FAQ's section till you understand what they are talking about. Read till you can't think any more and your eyes are bleeding. It's a learning process, and nobody is going to do it for you...might as well start learnin.

Quick Tips: Ask questions if you need something explained. Also, asking here before any purchases is likely a good idea. Tiz real easy to buy unnecessary crap some salesman say's you need. When planning your next grow, keep in mind that the flowering process is a tad different than the growth stage. Different nutrients, different lighting needs, different additives...Try to understand what you are getting into before you get into it. Ruins the surprise, but it keeps the plants happy knowing you are edumicating yourself on their behalf. :thumbsup:

tells me that you didn't read the post, or thread that I'm referring to.... Everything you said is correct,.. and I actually have been following it,.... save for the last few day's ( SEE MOTHER F'N THREAD! )

As far as I can tell I haven't fucked up,.... (Other than not tracking PH,... show me a thread where this happens due to a PH imbalance? :wtf: ).....


I know I F'd up somewhere, so please,... someone with the sack to read another thread tell me where!!!!:(

Rusty; I respect your input, but the details are all in my thread,... Should I quote my own thread into this one to sate you? :wtf:

I will if it makes you happy,..


what questions haven't been answered on the Q/A that I've already filled out?



I Know this is a bit of an Asshole post but my plant is dying before my eyes, and your not helping. :mad:

I just spent 10 min reading about your plants and all I can come up with Rusty already said.
peace

Second that!

Rusty's not always a sweetheart, but his words have iron.
He is usually spot-on with grow advice.

Aloha,
Weezard

P. S.:
If a plant wilts with more light, (not heat, but light), look to the roots.
More light = more transpiration.
Neemed roots no can, so plant wilts.

Respect...? :wtf: You've shown no respect.
I'm not going to learn for you, and I'm not going to hop all over the fuckin place chasing your info. Don't like it, tough shit. Without proper care, nutrients, lights, proper ph, etc...your plants are doomed. If another thread has further insight, it's your bad for not providing that info. Instead of this little spat over what you think you deserve, we could have been helping you to figure-out a way around the issues. But no. You chose the low road, and unfortunatelly, your laziness and selfishness has a direct effect on your plants.

Is there a reason you asked for help, yet sat back expecting us to gather all your details to save your ass? Is there a reason you were too lazy to help your own cause? Is there a reason you feel we owe you anything?

You can bitch and moan. You can blame and justify. You can lash-out and throw a fit. But your plants are still doomed without proper gardening techniques and a minimum standard as far as equipment and supplies. And did you know that as a newbie, your negative rep affected my reputation score by 1 point...? (out of thousands) It does add color to my boring green indicator lights though. I wonder how many of those newbie rep points you'd have left were I to return the favor...?

Go off and pout for a while, then do as instructed in the answers provided. It's a start, and you've a long way to go.

Please help! My plants all look great and I cant figure out why! Its driving me nuts. Gil

Ok thanks, let me know! :thumbsup:

:what:well, shit,... apparently I'm a douche, and need to put my girl out side because I don't know how to set up or control her environment.

I'm sure the overnight lows of mid 40-50's with Highs of barely into the 70's, and direct sun light won't hurt when she photo burns under 150 watts of illumination thats 2-5 feet away.:rolleyes:

Bit cynical, but that's what you guy's are saying :mad:


I know that I should be PHing the water, and I've finally got myself a test kit, and will next time I water her, but that's still 2 day's out at least, unless you think I should do something else.

Thank you Weezard, any advice on how to get the neem OUT of the soil and off the roots? as I posted in my thread, I may have F'd up the dosage. (more than likely since there's nothing out there about dosing the soil that I can find)

Repotting? more flushing? leave it the fuck alone and get her out of my shitty uncontrolled blacked out cabinet?



Thanks for the help Rusty ;)




Over night temps were 69.3 low 81.7 high with a 44% RH low, and RH peaked at 62%, lights are on 24-0 (shitty as they are, and as much as she can stand without burning) :rolleyes:

Just PH'd the tap water, and it's WAY high right from the tap, 8.5+ we have been letting it set out for a day or more before watering for the last few weeks. Still have to PH some water that's been setting, will post that this evening when I get home from work.


Thanks for the reply's all, this is a learning experience for me.

[quote=canniwhatsis]:what:well, shit,... apparently I'm a douche, and need to put my girl out side because I don't know how to set up or control her environment.


My humor is dark and I can be a smart ass ( I like me this way ).

FYI, I have watched my own girls turn brown and die, turn brown and not die, but almost, saw leaves with spots, burns and bugs and no roots.

It did take time for me to "get it". It also took some cash to get it right and then with reading, asking and more cash and then more reading, it began to take off.

Everyone I know has been there and done that. Dont get too discouraged. Just prepare your head to loose some plants. You will figure it all out in time.

Still learning. ;)

What part of this statement tells you I didn't read your post? The part where I tell you your incandescent lighting is inadequate, or the part where I warn you (and others that may be curious) about the grow spots? BTW...which page of the threasd did you specifically want us to go hunt down, or did you assume we had nothing better to do than read the thread in it's entirety...?

If you can't supply the basics like fresh air, heat removal, proper phing and nutrients...this will be nothing but a sour learning experience. No ammount of arguing or whining will change this. It's not that I don't like you, but I don't feel overwhelmingly obligated to doing someone else's job. It was your job to provide all relevant info so we can help you over the rough spots. Technically, you did a half-assed job. After completing the form, you get lazy...?

Rarely do I use 'kid gloves' when stating my thoughts. Bummer if it annoys you, but join the club. Doubtful the mod's like me much either.

Sorry Rusty, Just stressed out on my first grow after my plant about shit the bed.

Yeah, I did a half assed job in some respects, Lazy? No,.... Weeeeee bit drunk at that time of night tho! :glugglug:

I kinda figured you've got a wealth of knowledge crammed in that puddle of grey stuff between your ears, thanks for coming right out and telling me what I already knew. (poor lighting and needing certain amount of CO2 ect...)

Your No Candy Coating attitude came across as a bit harsh last night, but fuck it's a free country so have at it! :thumbsup: I'll try and not get miffed ;)

I grabbed the ears of a couple growers in my area today, and the consensus is that I F'd up with the Neem, and I shouldn't do that again. I really need to be PH'ing my water, even tho I'm vegging and in soil, It'll come back to haunt me later if I don't. I'm alright with the "actual" light (the T5's) that I have for now, tho I need to get her back under it ASAP! (As soon as the clones are rooted/dead)


How low of temps can I go? If I open my vents up even for a few minuets the temps fall into the mid to low 60's on a day like today, and humidity even with a humidifier running full blast will not break 35% I just don't have the heat sources in the booth yet to really need the vent's other than flow thru.

A buddy hooked me up with an old 150 watt MH in a bell style reflector, that's better right? Right now its about 4.5 feet from the plant, and I've got her off in one of the slightly darker corners I'll ease her into the more direct light and see what happens. Timer's back on the old schedule.

As a result there's enough of a heat source that I've got my exhaust fan running,(also on the timer to reduce night time heat loss) I'd guess it's pulling around 30 cfm thru the booth, (rated at 62, but it's pushing thru a long duct with several turns, so I've lost a lot of that) Better?

Also managed to find the one window fan that still works to get some better circulation in the main booth, Better?

PH of my tap water hasn't dropped much if at all by setting out,.... I'll need to get some PH DOWN this week,... soils still soaked from flushing, I'm not going to have to water for a while still I think, better?

The burns don't seem to be progressing as badly, if at all today, and the new growth is smelling like cannabis again. :jointsmile:

Temps with the light and fans on stayed around 75, humidity read 46%, but the thermometer is in the cabinet,... need to move that out next to the plant to get a better reading.



Note to self, never try and use neem on soil again! :o


Rusty, No hard feelings, I lashed out because I was totally stressed out, the move out of the little cabinet that I had under nearly perfect control (to my novice eyes anyway) and into the larger room was supposed to take longer than this, I didn't have any of the stuff accumulated to try and make the move, I could have kept her in the cabinet for another month. And I had my budget built around doing just that, I'm kinda hosed now. :o

Props to my bro on the MH hookup! :thumbsup:

Eeeewwwwwww. You drink alcohol? Yuck. (Anyhow, technically it's against site rules to discuss any drugs.)
Rarely do I get mad, but I am often...passionate.

Nice to see ya back.
-But-
regardless of the reason, we are all responsible for our posted words. No excuses the next day. "the dog ate my homework" or "I must have been drunk" are not valid excuses. (ok...life lesson over now)

The 150 is a much better tool than the cieling light and incandescents. You can still use the t-5's for side lighting, which would be a benefit. I keep my 1000 watter (enclosed hood, no cool tube) about 20" from the tops. Likely you can go much closer with your 150. I'd check and see how close to the light you can get your hand without disconfort. If your hand can take the heat for over 30 seconds, so can the plants. But best to ease into it over a day or so. This way you don't set 'em and forget 'em. Coming back to crispy buds would suck.

If you start seeking parts for the 150w unit now, you'll know where to get replacement parts and bulbs before they are necessary. (plan ahead)

Old growth is old news. Your leaves won't fully recover, but keep an eye on the new growth. That will be the indicator that you are on the right track. (or not)

You're going to need to feed tham pretty soon, too.

My ladies start to stress under 65ish. Somewhat more importantly, is keeping the difference in low and high temps to as narrow a range as possible. The plants seem to love consistentcy there. Proper ventilation is more important during the daylight hours. It's not nearly as important to vent during the night, as it is to vent during daylight hours.

So homework for the week...

Find an aquarium ph test kit, and some phDown. (freshwater) Do not adjust the ph unless you know the numbers, first.
Get some nutrients with an N-P-K proper for growing cannabis in it's two different cycles. Lower phosphorous for the growth phase, higher phosphorous for flowering. Canna or Fox Farms are a couple with good results.
Check prices for No-Pest srtips. Try and kill 'em before the need for more neem.
(no excuses that the dog ate your homework)

If your soil is holding water too much after a good soaking or flush, you might want to consider adding perlite to lighten-up the soil and/or turn-up the circulating fan a notch.

Good luck with 'em. Glad you got the HID light. You'll want to go even bigger once you see the difference. :thumbsup:

My Old growth leaves are stunted/burned, but will survive for a while, (I'm not worried about them, since...) the new growth leaves are looking strong and green and smell like cannabis!!!! :cool:

I wasn't planning on feeding or flowering for another couple months,... But I've learned that I over potted my plant,.... SEVERELY! (Clone straight into a 3 gallon pot) :mad: and of course there's a TON of problems associated with that. :(

My recent problems have me thinking of letting the soil fully dry and repotting in a smaller 2ish gallon pot for the moment, to let the plant get more root bound in the remaining soil before expanding into new turf..... :wtf:

Thoughts/opinions on repotting? I'm listening.

Thanks,... With the MH and Ballast in the booth temps stayed in the 70-80's,.... 40%-50% RH,.... Guess my first practical test of the vents proved more than just a little inaccurate! :o (not sure I trust my thermometer any more IMHO :wtf: )

turned the fan up a notch and made sure it's mostly blasting on the pot,... Hopefully the soil will dry out quicker.:jointsmile:

It's not that the HQI will necessarily hurt your plants, but it isn't at all optimal. Good for aquatic plants and animals, but not great for terrestrial plants. They run too hot, which means you can't get them close enough to promote healthy growth. Plus, they really are the wrong spectrum. The blue end of the spectrum for veg, red end for flower. 10,000k is a middle-of-the-road spectrum, often used to wash the blue from your fish tank. Gives more of a yellowish-green tint to the water, which some tank keepers prefer. (color-blindness...? IDK).

Yup. Would have been handy info, but that isn't the cause of your lighting and nutrient problems...;)
You are likely to have late-stage ph issues, since you will have been in the same pot forever.

No need to let the soil fully dry for transplant, just not too moist. :thumbsup: But regardless, at this point, it might cause more problems that it's worth. Shoving 3 gallons of shit (just a common phrase...don't get your panties in a wad) into a 2 gallon pot can damage roots and add another layer of stress. I'd ride out the error, and prevent it next time. :thumbsup:

A fan-forced exhaust is almost always better than fan-forced intake.

For clear liquids, sure.
Keep in mind with the drop testers, the result is color-coded. After you add nutrients or additives, it will skew the result. (red plus blue equals...9.2 ph? ...:eek: ) Likely not even in the ballpark. So do not depend on any ph readings, unless you are ph'ing a clear liquid. (water) This especially holds true if trying to ph the runoff. It doesn't work with the drops.

Either wait till your next regular transplant, or, adjust watering quantities and frequency, or...
How much room is there between the top of the rootball, and the top of the pot? If there's enough room, lift the plant out and add either straight perlite or your potting mix with 50% perlite. But make sure to leave enough room in the pot for future watering and feedings.

---

When a mix say's it's pre-ferted, it's usually a minimum of nutrients provided to keep the plants alive. But this doesn't mean they will thrive. Miracle Grow Potting Mix says it will last, what, 4 months? (I think...been a while) But in actuality, after a month or so I was having to start 1/2 doses of Fox Farms nutrients. (hint, hint)

I often change my fan angle and position in the growroom to get 'better' circulation, and avoid wind-burn.

If none of this helps, there's a link in my signature regarding a handy Bonsai re-vegging technique.
