I agree with the above posts that you are likely running too much light. There are some threads with PAR measurements on CFLs and various reflectors in the lighting sub-forum. I would check these out, and optimally, for DIY lighting, get access to a PAR meter for measurements. With the plants you listed, you probably want to be between 25 and under 50 on the PAR measurement.
I went the DIY cfl route and was blasting my tank with way too much light as well until I learned better lurking around here.
