GSP's having some major issues this week

[Deftec]

I've had this piece growing out for nearly a year now(my previous setup crashed, from which they were originally a small 2'' frag). It grew over to a separate rock, and I upgraded my system and put these out in one of the "frag/volume" tanks where they are separate from the larger system currently cycling.

Last week I had a bottle leak(Traction compound mixed with a little ether smelling substance) and the garage smelled like nail polish. I removed the bottle, and vented the garage for 2days after cleaning up. The leak happened within a matter of hours from the last time I went out there(about 4hrs). However, I can't say 100% that this is the issue due to not having any problems with any of my more sensitive corals or livestock. My sumps for the larger aquarium are also in there, and nothing in the display tank has had issues.
Due to this, I did a 50% water change over the course of several days(about 10g/day) and changed the carbon.

Within the last week they have gone from this:

To this:

Water tests are nearly perfect, and the lighting schedule has not changed at all.
125g tank:
Maxpect Razor LED's
Eheim thermostat

Water Parameters(tested 1hr before I posted this):

Salinity: 1.023
Temperature: 79.1 F
pH: 8.3
Nitrates: .25ppm
Nitrites: 0ppm
Phosphates: .25ppm
Ammonia: 0ppm
Calcium: 450ppm
Alk: 10dKH

Any ideas/suggestions would be GREATLY appreciated! Thanks.

Checked everything today. The left colony decided to open up, and now the right colony is closed, along with my hammer corals. Indecisive things!!! haha, figured I'll just let it runs its course over the weekend and see how they do. Temp was up to 79.7 F today.
