Check out this site, will give you a good idea what different LED's will do to your spectrum. I would definitely do different for the insides and the outsides if thats an option. With a 15 diode module, for the outsides (VEG) do something like 7 660 red, 2 625 red, 3 6500k white, 1 450 blue and 2 10000k white.
For the middle (bloom) Id do 4 2700k white, 1 6500k white and the rest 660 reds.
If you wanna do them all the same Id do something like 8 660 reds, 1 450 blue, 1 10000k white, 2 6500k white and 3 2700k white. I dont remember exactly what the limit is on the blues/whites for these but I think its 5-6 / module.
