Light question

I have 2 plants in flowering under 5x45W 2700k CFL and 1x85W 6500k CFL. Should i use the 85W cool white at all, if buying more bulbs is not an option?is it bad to flower with SOME white spectrum?

no, in fact i would advise using a mixed spectrum for all stages of plant growth. if anything i'd get a few more 6500k. like these extremely cheap ones with free shipping. its a hell of a deal.
