Once again, I will step in here and clear up a couple misconceptions.
Misconception #1 "If you use fluorescents for flower, you must use the expensive 'red' grow bulbs from the hydro store"...
Bullshit. You can grow just as well using compact fluorescent bulbs from MallWart or Home DePot.
Misconception #1-a "You must use warm white bulbs for flowering in a CFL grow".
Not necessarily. Your plant prefers a particular spectrum of light, but many combinations of colors from within that spectrum will make your plant grow. Ideally, you want as many colors as possible represented in your bulb choice. This is why so many of us use HPS, fluorescents, and MH together during flower.
So, if spectrum was the only consideration, you would want several bulbs of each color temperature (warm white, soft white, cool white, and daylight).
But spectrum isn't the only consideration. MUCH more important, is 'LUX'.
I won't bore you with math, but basically, LUX measures the intensity of lumens.
CFL's are low lux.
If you are using CFL's, you are already compromising many things. In the compromise between lux and spectrum, your plant will much prefer getting more lumens over more red in the spectrum it receives.
The CFL's that give the most LUX, are daylight bulbs.
The CFL's that give the widest spectrum, are daylight bulbs.
The CFL's that give the least LUX, are the expensive ones from the grow store.

If I was going to flower with less than 300W (actual) of CFL's, I would use daylight bulbs all the way through.
I would use as many as possible (ie. more lower wattage bulbs, vs. less higher wattage bulbs), and I would keep them as close to the plant as possible.
If I was using more than 300W, I might start thinking about adding one or two warm white bulbs.
