need help with my grow

[sk8sativa420]

this plant is 3 weeks old after the first 2 weeks the bottom two leaves started turning yellow i was spraying it with seltzer water and feeding it seltzer for about a week or so i stopped immediately after i found out it was draining the nutrients so i switched back to tap...what can i do to stop this and how can i make it healthy again?

this is week 1-2 and a couple pics from today

[Psycho4Bud]

Tell more.....lighting, soil mix, etc.....

They look a bit burnt to me.

Have a good grow!:jointsmile:

[sk8sativa420]

i am using miracle gro organic soil and a 100 watt compact flourescent bulb(26w) 24hr light cycle

[Unknownfigure]

Well, for one, you should try an 18/6 light cycle. And how far away is the light from the plant?

[lazy smoker7]

why whats so special about a 18/6 light schedule is it better than 24/o ? and is 24/o good anyways?

[sk8sativa420]

about 2 feet

[Number 1 DJ]

no way 18/6 is better cuz the plant needs some dark hours for its growth as well and ur gonna need more bulbs pretty soon thro in a 150 watt (42) when u can u will see vegitation increase and ur not supposed to use chemicals like mirical gro well i've heard early on its not to bad but i wouldnt advise keepin up with it. im not claimin to be a xpert or anything just keep readin other pplz logs to figure out what to do thats liek half the fun:thumbsup:

[Number 1 DJ]

hmm 2 feet... thats a bit far for that small and for only one 26 cfl i say nock the light down closer to a foot just make sure u can put ur hand right above the plant and not feel heat ventilation is also good

[Divestoned]

Those cfl's can get within a few inches of a plant...thas y ppl use them in cabinets....
The reason you want an 18/6 light schedule is becouse at night the plant concentrates on ROOT growth.also quit overwatering,your drowning her.

Dive:stoned:

[sk8sativa420]

well i put my hand above the plant and still feel heat why exactly am i seeing those little brown dots and another leaf has a shribbled tip

[sk8sativa420]

these are the pictures from today notice the shribbled tip i was talking about on one of the newer leaves with 3 needles[attachment=o152956]

[elway07]

are you feeding her a fertalizer? If so it is too early. She looks a bit fert burned. She is not getting enough light, and you are over watering her. water once, then when the soil is dry water again. Are ph balancing your water? There is a lot of info needed to help you out, but I think the person that stated you need to get the light closer was right. If it is a CFL bulb, you can indeed position it pretty darn close (inches) from the plant without hurting it.
Good luck,
Elway

[sk8sativa420]

i just moved it away from the plant recently it was inches away and it was drooping and burning it is now one foot away not two sorry i do water it once then when the soil is dry i water again i dont have a ph balance or measuring kit

[sk8sativa420]

im using a 24hour light cycle what do you prefer and i am also not using any fertilizers i used seltzer water that is why i think its burning or was and why is it still growing if there is not enough light...? what do you recomend i do about a bigger pot how soon should i transplant the plant is 3 weeks old tomorrow

[twoguysupnorth]

spraying it with the water and leaving the light on it after also might have caused the burns. if you are foiliar feeding it do it right before you turn off the lights. i dont know how your cfl was burning it, mine have actually grew right to the bulb and touched it without getting burnt.

Cannabis does not need any darkness during veg. That is a myth. Your *environment* may need the 6 hours of downtime, usually due to inadequate ventilation, to provide some time to cool down, but the plants do not. 24 hours of energy beamed at them during veg just makes them grow faster. If you don't like the speed at which they grow and wish to slow them down, or your ventilation/temps are inadequate to handle 24-hour lighting, then 18/6 makes sense.

As far as transplanting goes, I usually don't transplant until after I know the sex. Why waste growing media/soil on a male? When you do ultimately transplant, get some Fox Farm Ocean Forest soil, and use that in the new pot. I wouldn't use Miracle Gro ever again. I tried it once, had some probs. It doesn't even *look* like healthy soil, especially when you compare it to Ocean Forest, which is just the most awesome soil I have ever seen.

[sk8sativa420]

well now that i've stopped spraying it about 2 weeks ago why are little brown spots showing up

[jamstigator]

I've seen little brown spots resulting from heat stress. Happened last year when the power went out for 3 days, during 100-degree weather, poor plants suffered mightily.

[romdog11]

my plants had something like that going on and it was low nitrogen. i got some fox farm grow formula and that cleared the problem up. If it was damage due to the lights wouldnt it be on the top leaves? i thought it was the lights too but it was just low nitrogen.

[Deepsuthern]

i have encountered those brown spots before and it is a lack of some type of nutrient probly nitrogen... i've noticed that your plant didn't get long and stringy which means that the light was at a good spot... if its too far away the plant will start to "stretch" towards it.. a good way to tell if its too close is by putting the back of your hand under the bulb, if your hand is too hot for comfort then its too hot for your plant

If you search these forums, You'll find that some-one did the experiment to test that. There conclusion was that 18/6 actually produced a larger root. Larger roots = Larger plants = Larger yield. :smokin:
Not to be picky or anything but I was under that same impression until the results. :rasta:

[jamstigator]

*I* did the experiment, myself, to settle the matter once and for all, at least as far as I am concerned. Here's how I did it. First, I bought two identical cabinets from WalMart. I added identical fans and lights to them (4" axial fans, 125W blue CFL in each cabinet, that's 125 real watts, not equivalent, big ol' bulbs). I put clones from the same mother in each cabinet. I kept the temps at 70F ambient in the room containing both of the cabinets, around 77F inside the cabinets. I fed them the same nutes (Fox Farm Grow Big), starting the nutes on the same day. After four weeks, the plants running 24/0 were noticeably larger and more developed than the 18/6 plants. I don't know whether the 18/6 plants had bigger *roots* or not, as I was just concerned with which lighting regime produced bigger plants in the shortest amount of time.

That said, the 18/6 plants did not end up, after flowering, all *that* much smaller than the 24/0 plants. They were smaller, but not hugely so. The six 24/0 plants probably produced about an extra two ounces (total, for all six plants) over the 18/6 plants. Still, a couple of ounces is a couple of ounces, and I'd rather have them than not.

[Zcomp]

Well I haven't done this yet so I can only go on what I read but the experiment I'm reefering to only vegged for 10-Days(Hydro I believe) then pulled and measured each root. They also did a few on each side for variability(4 I think). It was a very well done experiment but that was only "there" results with "there" strain. If you believe in the 24/0 I say do-it. I personally wouldn't be able to swallow the 24/0. MJ wasn't born in nature with 24/0 so maybe there is unforeseen reasons for that, Natures "reasons". I totally support that extra couple O's, I'm just a worrisome putts. :jointsmile:

I am currently on a grow as I type this and my plants were on a 24/0 light schedule and I switched to 18/6. While my plants were in 24/0 they were growing slowly and seemed to just stop growing. Shortly after switching to 18/6 light schedule my plants almost doubled in size. Im not saying they grew bigger because I switched but it seems that way. Here have a look. http://boards.cannabis.com/grow-log/128203-d-rocks-t5-grow.html

Good luck with your grow and with what ever light schedule that you do decide to go with. Many growers have had great success with both light schedules.

[sk8sativa420]

i think my problem is nitrogen i bought a soil test kit and my ph was neutral but my nitrogen level was very very low so i bought some plant food with nitrogen it mixes in with water and it says feed seedlings and new growth every 2-4 weeks so hopefully my problem clears up soon

not enough or too much causing lockout? a build up of salts will stop your plant from taking the nutrient.Revised: The Complete Guide To Sick Plants,pH and Pest Troubles - PlanetGanja.com (http://www.planetganja.com/highsociety/showthread.php?t=8778)
