Would this be okay for one plant. I already have a thangy to putt that shit in rated for 600 watts *****. And I will have 2 CFL(50 watts). Or I could just get like 85 watts more of CFL, but that would be kinda gay because CFLs are no 1337.

I wouldn't put a 400 Watt bulb in a 600 Watt fixture. If you are going to run a 600 Watt fixture, you need a 600 Watt bulb. 600 Watts, or even 400 for that matter, seems like overkill for one plant. Seems like you would be wasting a lot of electricity generating light that the plant can't use. Good luck.
