Maze Brain Bleaching?

[chrisfont23]

Trying to figure out what is going on here. About 2 months ago I moved my maze brain lower in the tank to a rock where it could encrust. Looks like it might be bleaching. Params are as follows: Ca: 420 / Alk: 8 / NO3: 20 ppm / Am: 0 / Nitrite: 0. Everything else is in my signature.

Check out the pictures below. Specifically, the difference is the second one showing what looks like bleaching or discoloration on the brown portions of the coral.

Possibly just ticked it off because of the light variance. Give it some time to bounce back. I know your water is fine. So, if we break down what has been different, it would be the lighting, acclimating corals bleach out sometimes due to lighting.
