1 month of growth and color change

[mitra49]

I got an ora pearlberry and an ora red planet frag 1.5 months ago. The red planet is at the bottom of my tank the pearlberry at the top of my rockwork. Lighting is a maxspect razor nano led with a white/blue setting of 70/80 %. Flow is medium high via indirect mp 20. Parameters are as follows alk 10dkh, ca2+ 475, pH 8.0, nitrate and hanna phosphate - . I have a few monties growing well and some other newer sps frags looking good. Mostly I am concerned about the tan look of the pearlberry. I assume my lighting is insufficient causing the brownish color. Both frags are encrusting their plugs and seem to be growing / filling out. Any comments and advice is appreciated. Below are pics of each, the first being taken 8/4, the second 9/23.

Even the best LED lit SPS tanks don't typically have the best color. However, the colors should be better than that. The encrusting growth of the RP is not bad.

What are the N and P readings?

Nitrate and phospahte are both zero.

Looks like it's lightened up some, maybe feed a little more and see if you'll get it to color up some more. Doesn't look that tan to me, just a light purple color.
