3:1 vs all 27k

I've began the flowering stage for my 5 babies. Currently I'm using 14 cfls, all 27 Kelvins. I was wondering about the ratio of 27k's to 65k's. I've researched and found out that 3:1 seems to be the golden ratio for flowering and even vegging. The blue spectrum would make fluffier buds it seems, and red tighter buds. So I guess the golden ratio would make them just right lol.

So should I replace 4 of the cfls with 65k, or just leave them all at 27k?

I've researched more about this topic. Found some interesting information to share -

Should i use red and blue?
Red vs blue spectrum
Why use some 65k's when in flowering stage?

The spectrum mix for flowering is actually recommended for minimizing stretching, and more quality buds. So I've just switched 3 of the 65k's to 27k's. I wish I had done it at the start, they've stretched quite a bit now, oh well. :greenthumb:
