Looking at the pics, you could maybe lower the lights (unless you lifted them up for the pics, of course). 3 cfls will get you through the first week, but now they need more light, 2-3x more light at least...

Do you know about lumens and such? 3000 lumens (not K, like 2700k in the cfl) per square foot is the minimum, over 5000 lumens/sq.ft. and you are looking good...

Also you should wait until at least 5 alternating nodes before you use nutes, you could burn them. Not sure about the superthrive tho...
