I have no idea what's causing this but most of my 3 week old seedlings are yellowing, and some leaves are turning black at the tips and crumbling. It's not the soil because I've used it before, and I'm also using 2 different kinds of soil and it's happening in all the pots. However, 1 plant is doing great so that rules out the light being too close. It's a 600watt bulb and out of desperation I've moved it about 2.5 to 3 feet from the plants. I have no idea what is causing this. Any ideas?
what is your watering schedule?
are you over watering?
:)
If that was the problem I doubt some plants would be doing fine and others dying.Quote:

Overwatering either seedlings or clones will cause yellowing, wilting and ultimately dead tissue. I'd have to agree with Garden Knowm, Although I'm far from an expert.Quote:

My point is that some are doing fine. If I was over watering all the plants would be having problems.
