Hello magic, and welcome to the forums.
First of all, I believe your lights will be fine for veg, but as most would recommend, get an HPS light for flowering. Or you could switch to a warm white CFL when you are ready switch. I went to Canadian Tire and baught some 32w cool white spiral bubls for about $10. And they are working wonders on my plants.

Good luck with whatever you decide though
