Fluoro & CFL Combo 6500/2700 question

I have 6 girls (hope so!) soon to be going into flowering. I have a 6 tube T5 Fluorescent setup over top of them (all bulbs 6500k spectrum). They are about 5 weeks old.

I am thinking about adding a total of 6 separate clamp on 42 watt CFL's in 2700k spectrum to sort of surround the sides of the girls so they'd be getting 6500k from above and 2700k from the sides.

Do you think I need to also change some of the overhead fluorescents from 6500k to 2700k or just leave in the 6500k understanding I am adding the 2700k to the sides?

And what do you think of the idea overall?

Thanks for the GREAT forum!

Just my opinion, but I think the ideal combo would be 4 x 2700k plus 2 x 6500k tubes for flowering (in addition to the side cfls). From what I understand, the tops will also want to receive the 2700k spectrum, so if you can afford it, I'd replace 4 of the 6500k tubes with 2700k.
