Well what problems don't I have? I stretched my seedlings out by putting them too far away from a light. Yesterday I watered my seedlings with a very diluted mixture of superthrive and fox farms grow big. They are sitting about 8-10" under a 250 Watt MH. It is warm like probably 80-90 F in the cab they're sitting on, but there's a fan blowing straight at the light so it's not uncomfortable on the back of my hand when I set it an inch or two above the plants.

Anyway, my poor stretched plants (which currently have the two rounded leaves from the seeds, 2 more leaves, and then 2 little tiny feathery undeveloped leaves) have now started to turn yellow around the leaves. I thought this looked like it might be too little water, even though I just watered yesterday.

I watered them thoroughly with just plain H2O. What should I do? Are these things destined to die?

Also, I just bought the stuff to make myself a DWC setup. I'm thinking about switching these seedlings over to hydro if they survive. Can I just put the jiffy pot (with top soil) in my net basket surrounded with more rockwool? Would this make my plants more healthy than growing them in dirt?
