nano cube lighting help

[embryoguy]

question? i have prodominately zoos. and muschrooms. in a nanocube. ive been growing them under 24wt(50/50) stock lighting for the last 6 months. everything is doing fine, except for maybe one of my green zoos seem to fade and become more brown. i recently bought csl 32wt retrofit kit to add to the lighting .

 

i have 2 bulbs to use. a 32wt(50/50) or 32wt all actinic blue? i like the look of the true better for my zoos, but do you guys recommend i put in the 32(50/50) instead? is it necessary?

 

thanks in advance for all your thoughts.
