Brown tips and edges, pictures and data sheet

I have brown tips and edges burning but my stats are at what the makes of my food say... So I am not sure it is not a full blown wide spread problem just here and there it pops up and I don't want it to become a full blown problem.

Problem Sheet

First Hydro Grow


Your Equipment:
.1) Type and wattage of lights. (MH, HPS, CFL's, tube fluorescents, LED's) 300w HPS 1ft from tops, 300w CFL just above the plants
.2) Distance from tops?
.3) Reflector type? (cool tube set-up, bat wing, enclosed reflector, bare bulb...) CFLs Bare, HPS enclosed reflector
.4) Is there a consistent fresh air supply? yes
.5) Do you have an exhaust fan and a circulation fan? yes
.6) What are the bulb wattages, kelvin ratings, and schedule?24/7 HPS Guessing about 2400, and CLF 5500

Your medium:
.7) Specific brand and type of soil, (coco, peat based soilless...) and anything you've added to it. (vermiculite, perlite, worm castings...)Some are in coco sitting in the clay balls, and a few are in this white poly stuff â??seeing how the poly works it is cool had some aglea problems but is cool stuff.
.9) Did you use peat pucks (or similar) to root clones or germinate seedlings? Some seeds some clones

Your nutrients and water:
10) Source of water? (tap, bottled or filtered) What's it's ph before adjusting? Tap Water Ph befor 7-8
11) Method of checking water ph. (ph pen, test strips, aquarium test kit...)aquarium test kit
12) Method of adjusting water ph. (phosphoric acid, white vinegar, hydrated lime, PH Up...)Ph up, And Ph Down
13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule. Sensi Grow A&B it is a two part mix you add them Part A is 3.7-0-0 Part b is 2.5-2.2-5.7 Running at 600 ppm as recomended
14) How often are you watering between feedings, and how much per watering? hydro drip system some of my roots have made it to my tank so some of the roots are always wet but I am pushing lots of o2 into the water
15) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...) No but thinking of adding molasses?
16) Are your ph levels stable, or do they fluctuate?No my run off drops pumps up my adjusted Ph from 6.0 To 7-8
17) What is your ingoing water's ph?6.0 ...your runoff ph? 7-8
18) Do you foliar feed? If so, with what, how often, and at what time do you spray? not any more

Your growroom:
19) Indoors or outdoors? indoor hydro
20) What size of closet, room or hut?6x3x8
21) What are the temps and humidity levels while lights are on? temp about a constant 78 humidity not high ...With lights off?
22) Have you seen signs of insects in the growroom? Clean as a lab

Your strain:
23) What strain are you growing? (Indica dominate or Sativa dom?) some o.g. Kush and some carmel kush so both
24) From seeds or clones? some clones some seeds
25) Is this an autoflower strain? no

Try dropping your ppm's a tid bit and see if things improve. Some plants can be fussy

Peace,

Late last night I dropped them back to 500ppm... We will see how low do I drop them and if I drop them to much what will I start to see.

have you noticed if it's happening to plants in specific mediums?

i think coco can run the pH gambit from 6.3-7 (not positive). coco does need calmag+ (or molasses). with regular hydro you want 5.3-5.8. are they all running from the same res?

did you presoak the hydroton? this could be causing your pH to run up.

how are you getting runoff?

yes running same res. yes presoke, I built my own system so all my runoff goes into another bucket before for it goes back onto the pump it is a two chambered system so I am checking my run off ph out of the run off bucket.

The O.G. are having a harder time they are in the coco... 2 of the O.Gs have looked sick from the start odd clone cuts or just bad growing not sure. I will add molasses, and should I add H2o2 because the ends of my roots are in the water all the time or should I raise them out... I have a great deal of o2 going into my water via fish tank o2 pumps because of this.

gotcha.

how about the problems, are they in one type of media or the other? and you are mixing the coco and the hydroton?

the hydroton filled out the space in the pot for the coco clones to sit in. But I am seeing problems in both the poly and the coco/hydroton... The coco/hydroton is having more problems than the poly...

This makes me want to say pH problem...how about you Shake?

that's my best guess. coco and hydroton have different pH requirements (from what i've read at least).

that's where i would start. not to mention the coco needs calmag+ or molasses.

I killed one of my plants I think, I was adjusting the PH and the best guess is the first plant in line got a huge shot of acid it was crazy I just watched the thing loose pressure like a person it just wilted with in 15-20 and by two hours it got the dead plant bendy stem thing I have it flushing now but I don't think it can be saved I am so mad I should have turned the pump off for some reason as I put the stuff in it did not even cross my mind... But in truth I hope this is the case I have also read about fungus and other micro organisms killing your plants off but I don't think it is this fast more of a wasting thing. This plant has been week from the start and the shock I think just killed the little guy.

There's no use in saving weak genetics anyway...It's hard hearing you lost a plant, but it doesn't sound like it was a great loss.

plus you learned and gainde experience!

Thanks so much ya as for the plant death it sux but life goes on I just don't like to kill things, but I have a question what ratio of molasses to water should I go with... Also do you have any pointers on adding h202 to your mix.

I've never done a hydro grow but as for molasses and H202 i use 1 and a half teaspoon per gallon of water..hope this helps some as like i said i never did a hydro grow only soil grows..good luck and happy growing bro..:pimp:

Check the link in my siggy, inside you'll find a link under a post by Rusty Trichome that will lead you to a molasses guide.

As for H2O2, don't waste your time or money. Don't add it to your water because it mucks up pH and the roots don't absorb CO2 anyhow...

Here's a link to a forum thread on another site that has a few smart people who know what they're talking about discussing the futility of spraying or using carbonated water.

Soda/Seltzer Water as CO2 Spray

Best quote from thread:

"

You have to understand how CO2 is used by plants... CO2 is the plants air, as such there must be a certian amount in the air space around the leaves at all times in order for them to respire, just like we need oxygen, plants require carbon dioxide... And just like humans we breath in specialized ways through specialized organs, you could not just spray water, which contains oxygen, on your arm or face and think that your respitory system can make any use of it... A plant is the same they breathe through pours or stoma located on the underside of the leaves, the stoma only take in gases

Also breathing is not like eating, we don't have much control over breathing, it is basically controlled by our central nervous system, which we have very little control over, the more oxygen the cells require the more we automatically breathe... The point being that we do not not control our CNS and nor do plants, in order to influence things like this we must stimulate our peripheral nervous system in a way that they stimulate our CNS, so for example you can go jogging to increase your heart rate and oxygen intake... in plants we need to raise temps and increase waterings in order to stimulate CO2 transpiration, even in elevated CO2 environments

So to make a long story short, lol, spraying with carbonated water will benefit no more then plain ole' tap water, and it has nothing to do with CO2 transpiration.

"

SMG

I am confused because I thought it was more to keep root rot and things down... that is what I wish to use it for on my hydro drip it is a big fear because it is always wet have tons of 02 in the water but I heard that h202 also helps...

I can tell you that H202 will not help you prevent root rot. Just keep your hydro grow tank well oxygenated, light proof, and not drowning the roots and you and root rot should never have a problem. Keep your water clean and make sure you have it properly pH'd.

It has not hit me yet but what I worry about is that as my roots grow longer the bottoms are starting to live in their own run off water from the drip system. I do have tons of O2, but I also have some light leak in my system, so I guess fill those wholes would be my first course of action.

You want absolutely NO light in your reservoir tank! That can cause algal growth and you do NOT want that. As long as your airstones are pumping away, you really shouldn't have to worry about the roots. Keep your pH where it needs to be, watch your ppm's, flush often, watch for bugs, and don't worry about H202.

Maybe Shake will chime in with some other useful information.

I am good on all those fronts, and the light I am going to fix that sat. cool thanks for your time root rot is something that has been on my mind from the get go just because the system being drip never seems to dry out... Have you used different systems I am sure all have their problems. But which do you find to be the least trouble free.

Hempy buckets, hands down.
