35 Watt cfl(s) efficient?

I have 12 35 watt cfl lights.

I am only feeding the veg stage with 6 35Watt cfl 6500k lights, and then switching them to 6 35 watt 2700k for bloom.
I am growing 2 small plants. I need to know one last thing before i continue. When i veg do i veg completely with 6500k cfls or do i mix em up a bit with the majority being 6500k?
