Okay my first CFL grow in a nut shell.
Get as many blue lights (6500k) as I can muster. Start 12 plants under 6 23w 6500k bulbs. As the plants fill out and become less manageable add 2700k lights for mor red spectrum.
Once 12 plants were about 10 inches I started flowering them. Once sex showed I eliminated 7 of them. This gave plenty of space to the remaining females. If you feel an area needs more light then get a new light.
The flowering period can take as few as 8-10 weeks and go for as long as 14ish. I have had plants take almost 16 weeks including the stretch at begining of flower.
Also as you are adding lights you can think about reducing the hours slowly over say a month or even two weeks. I feel plants respond to this rather then being thrown from one light schedule to another..
