Coloring up green hammers and red acros

[GHOSTLY]

Acro:
As most of my acros settle in i notice that they develop a nice red but never go beyond to full red (usually settling half green.) After going from full brown to this They seem to have stopped here. Is there any way to emphasize and pull out deeper reds? Ive got a g4 radion at 74% and par
No3 5
Po4 0.1

Hammers
Ive noticed both my hammers have started to split and become bicolors. A very feint green is seen in them and my question is if there is any way to further emphasize and bring out those greens such as feeding or lighting

I’d increase my PAR to get more red and less green.
