Hi and welcome, your plants look nice and healthy but I'm not quite sure if the positioning of your CFL is very optimized. Do you have any equipment to measure light output/lux/lumens? I've never measured it myself but I'm pretty sure you'd get much more light intensity if you hung the lamp horizontally.
That's also the only thing I noticed that didn't look quite right about your plants; they look a little bit stretched, not much but noticeably; which is a tell-tale symbol of too little light, which usually comes from CFLs being hung too high and like I said I don't think the position is helping.
You should think about hanging that lamp - depending on power and temperatures of course - around 24" or 60cm away from the plants, you can go closer if the temps are low enough and you'd like the plants to not stretch too much.
A little more data on your setup would indeed be helpful though.
Good luck with the grow man :gthumb:
