My first thought is that you are going to want to read up on the lights. I'm not good with CFL stuff. I kind of ignore it as it doesn't apply to my situation. However, I'm thinking you are going to want more lights and you want to be sure you have covered the correct spectra.

How many plants and what is the strain? My concern would be that they may overgrow the space.

There are others who know nutes much better than I.

Pics will help.
