It is best if you use 6500k cfl bulbs...Thats what I have and they work great! And for budding use 2700k cfl bulbs.Most people who veg with CFLs choose 6400k ones and for flowering, 2700k ones. IT doesn't hurt when flowering to leave a couple of 6400k in there either.
Lookin good too - looks very healthy - nice colour and the LST looks good.
I have 5 plants on their way and a few looking like yours. Im guessing my problem is that its about 95 degrees in my room(90 with the lights off)(CFLs). Suckswhat are the temps inside of the room ?
