put more soil in the pots, they are stretched like that because the soil line is too low. Get some organic soil thats guaranteed not to burn that has worm castings, unsteamed bat guano, perlite, and peat moss at least. hopefully it has more but not too much more, I recommend to typically stay away from Miracle Gro, as I have seen way too many people having trouble with it. You could go steal some soil from a farm row and test its ph if your broke or something... put a flourescent light about six inches above them until the stocks strengthen up a bit and there is a couple of set of leaves.... hope that helps anyways... no nutes for two weeks,and the coloration: its probably too hot for them, you could put them in a place thats shaded slightly in the afternoons, or put a screen above them...
