CFL lighting spectrum question

I understand that vegging likes 6500K and flowering enjoys 2700K. Currently I only have 6500K spectrum on it. I'll be turning it to flowering here soon but was wondering if I should keep the lights in there now and just add 2700K ones or take them all out and only supply it with the 2700K spectrum?

add red keep blue too,the more the better.

will do sir. thank you.
