Can't say I am an expert, but my recent indoor grows used up to 8 60 watt 6500K CFLs for first half (autoflower), then changed the bulbs to 60 watt 2700K for remainder. Had huge colas, dense buds, and no serious issues. I used splitters on the 4 light fixtures, and spent time each day or so adjusting lights to be as close to all parts of plant (without burning). I enjoyed giving these first grows this extra attention, and I'm happy with results. Good luck with yours!
