Kush Bag seeds

1st time grower

I have a Cfl set up with 3 100 watt 6500k bulbs

MG soil time release mixed with some speg. peat moss

12"L x 12"w x 18"h box with foil for reflection

filtered water allowed to sit out for 24hrs

temp in grow space is 77-83 f lights on
65-70 f lights off

ph of soil is 7.5 maybe a lil higher
ph of water is around 7.3-7.5

small fan

My ? is i have 2 seedlings that are aprox. 6 days from seed. Both seem to

have slow growth up to now. Both have 1 set of leaves working on pushing the second set up. But ive noticed on 1 of the seedlings that it has started

to lose a little color, turning pale green to almost yellow in color. i was

thinking maybe its because of p.h being in the high 7's. but ive also read on

here that people have used 8 p.h water with mg soil with no big problems.

either way i water them every other day or every 3 days when i feel it is

appropriate. but maybe its the time release soil that im using. strange

because these problems didn't arise till day 4. both seedlings are around only a 1 1.5 inches high. i have the lights maybe 2-3 inches max from the top of plants.

maybe im just bugging but are my plants small for 6 days or what. ill take any help and suggestions i can get. lay the info on me. :rastasmoke:

looks like the nutes in the mg soil is alittle to much for there young age.Next time fill your cups up with a soil with no nutes. Or bottom half mg. top half with no nutes. Also can start in peat pellets then place into mg soil after a week or when ever roots penatrate bottom I alway cut the netting on the bottom of the peat pellet after it swells, But before putiing seeds in. This assures the roots will pass with ease..

My local nursery closed it's doors, and now I'm back in Miracle Grow. I've got wellwater that comes out of the tap at 7.9 ph. NEVER would I try and use that water without first properly ph'ing it. Perhaps were I growing outdoors, but that's a different animal.

I germinate the seeds in a paper towel.
I set-up my cups of MG soil.
I flush the shit out of the soil. (3-4 times the volume of the cup, with properly ph'd water)
Once seeds crack open, I poke a 1/8 inch depression in the soil, place the seed in the depression, and cover with soil. (the soil should still be wet enough from the flushes)
Watch the soil closely, and water if/when necessary. Use care when watering, as you can bury the seeds deeper.
After the 4th or 5th set of leaves, 1/2 doses of growth nutrients, and watch their reaction. If leaf margins get brown (overfertilizing) wait another two weeks before the next 1/2 dose of nutrients.

Once the plant is mature enough for flowering, you'll want to think about it's final transplant. In MG I do my final transplant a week before switching to let the immediate release nitrogen in the soil to do it's thing for the last of the growth phase. If you wait till switching to 12/12 before transplanting, you can delay the flowering process till the plant is damn good and ready, and the immediate-released nitrogen is used-up. (after the initial nitrogen release, the nutrients in the MG soils are quazi-balanced from that point, forward)

Young sedlings might struggle a tad, but they usually recover if allowed to do so. Don't 'overtend' them with additives, tea's or other crap. Usually you'll do more harm than good.

yeah i was thinking the same thing too, But i don't know why it wouldn't show up b4 now. So what would be a recommended i do to fix this problem? what about the size do they looked stunt? they are only 1.5 inches in height, i did get these seeds out of a bag of og kush. so maybe there just shitty seeds. Any more suggestions?:jointsmile:

Thanks for replies...in advance:thumbsup:

edit: Or should i just wait till i do my last transplant to take care of this problem. im going to keep this tread open prolly till my problem is fixed or i transplant to final container. thanks again

bump: Should i also switch it to 24/0 lighting. im currently using the 18/6 lighting. Wich is more recommended? I want to increase the size of the plant, Will that do it ?

Rusty Trichome

10-01-2010, 12:16 AM

Some folks run a 24/0 schedule, but I prefer a 18/6 schedule. My plants seem to do better when they are allowed to enjoy a dark period.

The plants look fine to me. And given proper care and some time...they should be even more fine. Patience is an important tool. Use it with abundance. (unless something goes wrong, of course...in which case it's ok to panic) Overwatering and overfertilization will stunt your meds.

Miracle Grow soils can be tricky and tempermental. It's no better and no worse than any other soil you'd have to learn how to use. But, some folks online still bash the stuff. Those gardeners have obviously never grown cannabis in MG, so I put them on my "just another parrot" list. Those without experience parrot (mindlessly repeat) shit they've heard, and are generally full of all sorts of other useless information.

With MG, generally, you'll use less nutrients almost all the way through to harvest, but you'll will need a micronutrient source. I use the Fox Farms Trio of nutrients, which has most of everything you need, and a handy weekly feeding chart. Unsulphered molasses from mid-flowering to harvest. Great source of calcium, magnesium, some micro's, plenty of iron and carbon, and carbs.

Watch for ph issues late in flower. The buffers will eventually fade-away making the ph take a dive. (raising water ph is the most likely remedy, but make sure it's a ph thing first) But being a 6 month formula, I'm not sure what I'll encounter in regards to ph stability. (my seedlings are 3 true sets of leaves old right now)

With MG, I always save the soil from plants I've vegged, that turned-out male. I use this soil for the final transplant. It's basically the same as flushing-out new soil.

I'm no MG guru, but it's what I learned how to grow cannabis with. (many years ago) Only difference is...now it's a 6 month time-release formula instead of a 3 month. So technically I'm still learning the new formula, but I've done ok with it so far. No issues at all.

Thanks again for so much info. i was hoping that you were gonna comment on

my thread, Ive read so many threads on here and out of a alot of people you

seem to out give the most accurate advice:thumbsup:. So i thank you again.

I plan on just waiting it out for a couple days and then go from there. yeah im trying not to try and over do it on them, but i feel like im in love:s2:l

lol but i guess i have to wait and see, ill post sum pictures either tomorrow or the next day depending on the situation.:rasta:

Another ? hows the yield on these cfls?(2300k) just a random question

But don't let that detour people from leaving comments and or suggestions. ill take all the advice i can get.;)

bump:
another quick ? for anyone, When it comes to CFLs i use the 100 watt equivalent bulbs. What is the difference between these and a real 100 watt bulb? lumens?

and if so could i make up for the difference with more bulbs or should i just go get the real thing. This is my first grow so i want to optimize my grow to be the best it can be for CFL.
Because i plan to flower the medicine under CFL too , So i wanna figure out this before i go by some 2300ks. full wattage or multiple equivalent wattage's?

Thank you everyone who may help out. (gotta love us newbies)

I have learned to adapt to scotts premium. It work we ll with low maint. Autoflower weeks4-7 1/4 strength mg. weeks 8-9 flush.Able to aquire better taste with agressive flushing. well good luck Also i go by actual watt when it comes to cfl. But i could be wrong i no longer use them..

10-01-2010, 03:31 AM

My lights just came back on my 18/6 timing, So i figured id take a gander in the box i have. And it looks like the other side of the plant<opposite leaf> is starting to turn that yellowish color:mad:.

Should i flush on my next water:question: or is it some how my water, that has a p.h of 7.5:question: it has new growth on it that hasn't yellowed so I'm confused.

ill get some pictures up tomorrow. Unless you guys have any ideas........ or you can refer to the first pictures those are only a couple hours old.:rasta:

Only time can tell:blueknife:

My only 2 seeds, I'm trying for the least amount of stress to induce a higher percentage of female sex. I love my bitches.. Lol pertaining to my medicine. no offense to any ladies.:weedpoke:

Thanks bob and rusty for the help so far:thumbsup:

I am a bad teacher, But dont over think things. Rusty is the man to talk to. I would try to improve your water source. I changed water source for a week and through everything outta whack . Water ph is important. fresh running spring water ph better for me then the well does on my end. You will get it hang i there...

seventhchild

10-01-2010, 11:05 AM

in addition to adjusting the ph of your water i would also suggest that you move those lights AWAY from your babies..........6'' from top of plant ...too much light to a just sprouted seedling will cause seriously stress .after it grows two or three sets of true leaf [and is healthy ] move the lights closer.always treat your babies as babies...no full strength anything.

plants look their age. mine look nearly identical and I am also at day 6 in miracle gro. quick growth can be expected within a week or so from my experience.

Been trying to post a picture of my plants in Miracle Grow soil, but it seems the site is still having photo upload issues. I did manage to post the picture of my seedlings in my photo album, if interested.

what age are those rusty?

doeboy742

10-01-2010, 06:34 PM

I was thinking that it might be the lights being to close to i have them at about 1.5 to 2" away. So i should move the lights further away?

I also had that 1 plant close to the ballast of the light bulb for a day before i had a fan. I looked today and it still looks like the 1 baby is going down hill still. so ill move the lights further away. I was thinking nutes from the MG soil, but why wouldn't it affect both?

i was thinking humidity was a problem from the beginning. I should have put them in a humidity dome till week 1 was over. My mistake and l'm paying for it now.:(

Thanks for the input guys:thumbsup:

Keep it coming, Nothing much changed with those babies so ill give it a day and post a picture tomorrow..

RUSTY: looking good man. Those are under Cfl's? And what do you think about me moving the lights aways back?

doeboy742

10-01-2010, 07:11 PM

I figured i add a couple of pictures of day 7. Take a look guys and let me know what you think.

Moved the lamps to about 3" is stead of 1.5".

Added water bowl for humidity

If you look at plant #2 in the picture and compare to day 6 pictures you can see that the yellowing has spread a lil bit. But the Plant labeled #1 has no yellowing at all.

Either way thanks, and ill be looking forward to you guys response:rastasmoke:

Edit: By the way took down the foil replaced with white paper. Hopefully that makes a lil difference in temp(cooler) and light reflectivity.

Rusty Trichome

10-01-2010, 07:36 PM

I'd really rather not hijack this thread, but will be starting a MG grow log if and when the attachment feature is repaired.

Yup, CFL's for early vegging. I think there's 8 of 'em on, but I've got 10 bulbs available on that rack. CFL's light is only effective to about 6 inches, maximum. I wouldn't get all anal about unusable reflected light. (the light has to travel from the bulb to the wall, bounce off the wall, and get to the plant. Technically too far for CFL light) But good job removing the foil.

I keep 'em about 4" away from the tops. With that many bulbs, heat builds-up quickly. Were you talking about the semi hot 23w CFL's (100w equivalent) or the 100w CFL's which are brutal hot? Makes a big difference.

Young seedlings and clones appreciate an extra inch or two of space, but after a week or so I let them 'grow up' to the 4" buffer-space mark, and maintain that distance till ready for the late-veg HPS. They quickly adapt.

I always use a fan from day one. (Seedlings only. Unrooted clones do best in a dome)

Mine are something like 2 or 2.5 weeks old...? Not too sure. Years ago I stopped worrying about how old they are, and started looking more to when they are ready for the next feeding, transplant or harvest. I'm impatient enough without clicking-off the days on a calendar. Not a recommended tactic for the inexperienced, as knowing your plants are right on track is comforting.

Don't keep the rootball saturated, it'll stunt the plants and cause problems. I keep my humidity low on purpose. Hot, humid air provides the perfect enviornment for mold. Heck...I don't even spray 'em unless I have to. Pre watering I'm at around 30% relative humidity. Post watering I'm about 50% RH. (in the growth closet)

I don't mind at all :jointsmile:

I like all the input i can get from everyone. This all is a learning experience for me, So the more knowledge the better.:rastasmoke:

So feel free to post threads and to link other threads and put any info you you will be of any help . The last thing i'm concern with is thread jacking.

So post pics, info , links and or anything you feel will be appropriate.

Thanks again for everything guys:thumbsup:

michaelpeg

10-02-2010, 04:08 PM

I also dont mean to thread jack but one quick question, Rusty can't wait for the log and are you using the miracle gro with the orange pellet plant food or the liquid filled balls?

doeboy742

10-02-2010, 06:07 PM

Actually I think they are yellow balls filled with some kind of powder looks like to me. I found one one the top soil and broke it and it was filled with a white powder.

Actually I may have been over watering them a bit, I have a moisture reader and it still says wet and I haven't watered in 3 days. But by looking at the plants they look like their liking it. Leaves peeking up towards the light, a lot of the drooping has since disappeared.

I'll post some pictures tomorrow to show you guys, and let me know what yall think.

Thanks again everyone. And stop worrying about thread jacking. I give anyone whom wants to post anything, to do so.:thumbsup:

10-04-2010, 12:30 AM

Was refering to ME hijacking the thread. Bad habit to get into, as some take offense and it's bad etiquette. Not sure about the time release pellets, I hadn't checked. Flower shed is closed for the night, and that's where I keep all my supplies. I do know there are orange pellets in the mix though. Looks like minature caviar. (as Rusty throws-up in mouth)

doeboy: Glad to hear they're perking up. Just holler if you need anything else. :thumbsup:

doeboy742

10-04-2010, 03:26 AM

Still for some reason on my bigger plant i still have the yellowing. I flushed both pots with straight water.

Still have no pH adjuster so this might be my problem, Even though my 1 plant still has green growth. But the (cotyledons) on the smaller plant have seen to start yellowing.

Is this because i flushed?

Either way thanks for the feed back here are some new pictures i took today...

Need your help rusty!!:thumbsup:

Looks pretty normal for a seedling in Miracle Grow. Every time you water, you are releasing some of the nutrients into the soil, which the seedlings are having to deal with.

Do not keep flushing. Ingoing water ph should be between 6.3 and 6.8ish. How did you determine that your water ph is in the 7.3ish range?

In an emergency, you can use vinegar (works ok for emergencies) or lemon juice (not for long-term use) to lower the ph a tad, but it's best to get some phDown (General Hydroponics) or something similar that's made for lowering botanical ph, for the long-haul. Wait till their next watering to make these adjustments. But nothing I've seen in your seedlings screams "emergency" yet. Relax.

doeboy742

10-04-2010, 05:31 PM

Thats what my ph was before. I just checked it its at 7.6 mabyw 7.5 but its up there. No I know its not a emergency just worried about my babies. Lol, I have a ph probe that I got from home depot.

I don't think it works to well. It's the light/moisture/pH probe. But ill let them go ill take a picture at week 2 and post it. Or if I have another problem by then. But again thanks a lot rusty.:jointsmile:

Rusty Trichome

10-04-2010, 06:10 PM

You'd be much better served getting a freshwater aquarium ph test kit, ($7.00 or so) or a ph pen if you can afford it. Either way, find out your water ph asap. Not an emergency yet, but the potential for BIG problems is there, and knowing your accurate ph is essential. Most folks in the USA can go online and check their local municipal water quality report. It'll have all your ph info there and is at least in the ballpark of accuracy. Google "Water quality report" and your town's name and and your state. For instance, mine would be Water quality report East Anytown, Arizona. Or something like that.

Those soil probes are the most unreliable pieces of crap I've ever purchased for the grow room. Absolutely useless. (no offense intended, lol)
