One of your problems is that your plants are too deep in the pots. The plants need good air circulation. Unfortunately, there's not a whole of a lot you can do about that right now. Any roots are so tender they would tear apart if disturbed. You need to get a fan blowing some air around - below the lights and on the plants.

I don't grow in soil, so I don't know what your other problems might be. But do get some air circulation ASAP.
