Space invader pectins losing color

[Moneymitch]

Within the past 3 days the underside of my pectina has been loosing color. It has been in my tank for about 2 months now. I just moved it to the bottom of the tank to give it a little less light. The system was at 0 nitrate and I did a broadcast feed of reef roids which spiked it. It is still puffy with its tentacles out almost 24/7

My parameters are good all except mag as I do not have a test kit but is on its way.
Ph-8.3
Nitrate-20
Nitrite/ammonia- 0
Calcium-480

Currently running a 125 gallon mixed reef tank with wills lighting. Do add formula 28 cubes for trace elements with 30 gallon water changes about every 10 days. System has a light bio load

what kind of light do you have? IME, losing color but still extending and showing polyps is usually due to weak light or insuficient color spectrum.

I am using Wills. I know they aren’t top of the line all of my other corals are doing fine but all are growing at a very slow rate
