looks like your plants have 2 or 3 sets of true leaves,get a small fan blowing over the tops , at the bottom of the lights.At that stage 2" with a small fan blowing over tops ,should be fine,theres a fine line with cfls,those ones that are "praying" are loving the light and could stand more.I start seedlings with a 42 watt cfl at least 6 to 8 " above light as they develop 2nd set of true leaves I lower the light gradually and add a small fan.You can tell if they are loving the light if they grow to it or shy away (leaves curl, almost droopy,not liking it if so back it off) its not the light of a cfl that gets them its the heat, small fan over tops key.don't use any nutes with ffof until at least 3 weeks or you will burn them.
