My plants were nice and green till 3 days before. Now 17th day from seed. And leaves were going to be yellow so fast in 3 days. I started with cfl lights and 15th day I see some of lower leaves going to be yellow. And I thought it was lack of light, I changed system to 400 watt MH. Light is 110 cm over plants. And in 2 days all plants lower leaves turned yellow. Also sone of upper leaves turned yellow too. I thought it may be overwatering. But they are going really bad. I will upload pictures and maybe you can help. Light burn, overwatering, underwatering, need nutrition, ph problem?
Please help and save these plants… Thank you…

All of are same… Can I heal them? I bought something for yellow leaves. It says 5 ml to 1 liter water. And spray to leaves for fast recovery. It can absorb from leaves immediately. I will try it tonight when I turn off lights. Or can I spray it while light is on. I dont want to harm leaves any more. % 1.65 nitrogen, % 1 fe, % 2.25 mg. (Spray solution formula)
Mine looked like that and it was Nitrogen deficiency, although mine where a bit older. So your spray should work. I gave mine a high dose of nutes and that stopped the yellowing. The yellow never went back to green so I just pulled the leaves.
Either Nute burn if you just fed/or dificancy if you haven’t. or too close to your bulbs.
I had the same happen to my plants, not quite as bad. I never found out what it was, but just raised my light a bit and with my next water I gave it just water at 6.5. I did put seaweed extract in the water before the blotches, and it made then shoot up and almost touch my cfl. Hence I couldn’t tell if it was the seaweed or the heat.
The plant recovered fire, but the few leaves affected ended up getting the Chop once I seen new growth. The leave was ruining their beauty shots.
I am new member so yesterday my messages were limited. So I couldn’t answer. Thank you for all of your advices. Do you think that this plants will be good again?
@bryan Actually I checked old pictures and remember now that I changed light after yellowing started. And then it turned yellow faster in 2 days.
@MAXHeadRoom@Fever@Majiktoker@TheDuke Thank you. I am again with Cfls. I put them a bit higher. I sprayed yesterday night and tonight again. I also gave nutritions for plants with green leaves.
@Dr.DankThumb420 I also thought about it and made holes bigger 2 days ago when I just saw this yellowing start. And a bit water came from bottom. May it be about it too? Now holes are bigger and drainage is good after watering with nutritions.
@Donaldj I use again cfls and temp lowered to 23 celcius now.
@TokersHaven Just ready soil and torf mix. I dont know details. I am just beginner.
@Rugar89 I am beginner. Do I need to check Ph of water which I use for watering? Or ph of water coming under pot after watering? Or soil ph? I was using bottled water and ph is 7.4. Is it too high?
@Majiktoker Thank you. I will check it and try to stabilize at 6.8. And they are in 5 liter pots now but I want to repot them to 10 liters or more. Do you think that I must wait till they are strong again and then repot? Or will they be healthier faster if I repot them with more quality soil mix for green leave plants in bigger pots?
