What's wrong? (Yellow and black leaves)
I have lots of seedlings growing under CFLs, much like I did last year. 2013 was my first year, and things went pretty smooth. Now my seedlings are under-developed, some have yellow leaves, some have black leaves, and a few look entirely stunted and have even started dropping leaves. I have no idea what's wrong. I'm pretty confident I don't overwater, and I also don't think I am underwatering. The CFLs are 30w, and don't give off too much heat. Could they be cooking anyway? Any other suggestions?
This one is quite healthy:
