I have had these little guys, well hopefully girls..going for about 3 weeks and the problem started with the plant you see with the white leaf, it was my most vigorous sprout and as I was hardening them off outside I thought he mightve gotten a little too much direct sunlight causing a scorching of the leaf. But then i noticed that problem on a few other leaves and thought the same thing. I am growing them in plain potting soil and watering every few days as the small pots dry out...Recently they haven't been growing as vigorously as I expect them too and they started getting pretty light green and at this point also noticed a few second and third leaf sets coming in yellow. So, i figured at this point that it may be a nute deficiency and that a very diluted foliage feed may be in order..I misted them just a bit before lights came on in the early morning as directed by a few sites and the problem is persisting and appears to be deteriorating my babies quite quickly. Heres some info that might help you out.

Using plain potting soil as i said mixed well with perlite, nothing else. Under a 400 watt MH setup thats a little over 2 ft above the plants and a fan oscilating on them to keep them tough and keep the air circulating. Only thing ive done differently in this grow from any other is the use of those little biodegradable containers that you can see and the hardening off outside..everytime i do that the next day they seem really beat up and problematic even when i do it right. I dont know what's going on here, but this is my test run for my actually genetic based seeds and I don't want to have problems like this with those..Any advice is greatly appreciated, if you need more info just ask. Thanks a lot.​

What kind of soil are they planted in? It could be that they are nute burned, doesnt really look like a defficency. IF they are in miracle grow or something, the soil could be too strong for those little babys. Could be wrong tho. Also it is kind of hard to see because the light is on when you are taking your pictures. Are the leaves curled up around the edges at all? Are they turning brown or yellow around the edges at all?

Plain potting soil, mentioned that twice above I beleive..Yeah sorry about the shitty pictures, but yeah there are a few plants with yellow/browning cotelydons and some have the top leaves browning, curlings around the edges. Most just have the top leaf problems, but it sounds like i may have more than one issue. Idk..what do you think?

yeah sorry about asking about ur soil, i accidently overlooked that. I would say it sounds like nute burn but since you are not using any nutes it is kind of confusing to me. You should take a look at your potting soil and see if it says something like realease of nutrients over 4 months, or slow realease nutrients or something. Also look at what the N-P-K content of your soil is. If its something like 15-30-15, then you have found your problem.
