Additive and supplements

Alright I've been working on my nano getting it running alot smoother better lighting and more flow. But my sps are still not coloring up the way they do in the rest of my tanks.
Current parameters

CA 440
Mag 1420
Alk 8.3
Po4 .5
No3 4
PH 8.3
Temp 76.2
Lighting is a hydra 26 HD running at 58% about 14 inches above the tank. I dose Red Sea coral colors and brightwell 3 part concentrated solutions. Salt is fritz pro water change weekly. Filtration I use chemipure blue.
Figured I would get all that out there cause I know it's the things I always ask before I make recommendations.
So what would you recommend for best coral coloration and coral growth in a nano and why.

Given that you have other tanks, and are basing your results off of those, what is different from this tank to those, aside from water volume?

I treat them all the same dose accordingly I do dose this tank by hand though as it does not consume nearly as much as the others and dose maybe once a week in between WC.
And the chemipure blue. The other tanks I run reactors for carbon and GFO.

How old is the tank?
