Birdsnest bleaching

[Krixic]

Hi, i have a metalic green birds nest (it might accually be an acro....Confuse the two) I got a week ago. Everything else in the tank is doing fine including a couple random acros, stylophora, tubbs birdsnest and some softies. But this one guy is bleaching up. My parameters look fine....Ill need chdck again once I get home. Last I checked a couple days ago and salinity was a tad lower than usual at 1.024, nitrates at 10ppm and phophates at .05. Temp fluctuates between 77 and 79 throughout the day. Is there anything I can do? I'm using a Kessil 360WE tuna and slowly raised intensity from 10% to about 60% over the course of a week. Mix of blues and whites.

Here's a few pics. One of the bleeching coral and another of the ones doing fine

Any pictures to help you out a little bit better to see what’s going on?

Also there's like some hair like material on the right end tips of the coral. Not sure whats up with that
