I guess I'm the resident CFL expert so I'll chime in.

The 5000k lights your using won't really yield any results that aren't sub par, CFL's range from 1900k to 7500k, the most common spectrums being 2.7k 5k and 6.5k, 5k is a neutral light, for veg you want bright white, or the 6.5k's, and when your plants get bigger you want the warm 2.7k's. 5k is just like a halogen which is why we don't suggest using halogens to grow, the light doesn't benefit your plant.

Switch bulbs, and you'll see alot more progress
