I hope that helps

Have you double checked salinity with another refractometer? I've almost wiped out a tank slowly with a broken refractometer, Just a guess. looks like something is irritating everything as even the trumpet coral looks to be receding.

Sure hope you figure it out tanks beautiful.

Your tank setup looks fine, but your tank has been through a lot of changes in the last 6 months including light changes, changing from dosing to a calcium reactor, alk fluctuations and the use of carbon dosing plus you have a mixture of lps and sps. You didn't mention if you were using activated carbon, so that may be a good idea to compensate for the allelopathy (chemical warfare) between your corals.
Bottom line I think your tank needs some stability, but start with a regular water change schedule.
Turn down the lights and increase water circulation. Water circulation is as important, if not more important than lighting.
imo

I just recalibrated the refractometer and the tank is sitting at 1.024

Iceman you said you neglected the RO filters my guess is chorine got into the tank.

Just what I was thinking... How aggressively were u dosing AF? And what products?

I was dosing aquaforest reef salt
aquaforest calcium
Aquaforest magnesium
Aquafores component strong
Aquaforest reef mineral salt
Aquaforest amino acids
Aquaforest bacteria

I followed the directions for all of them and never had an issue before.

Was using the same things at full ( recommended) doses... Had a similar issue which resulted in the loss of all my sps... i think the corals got stressed and stopped using all the micro elements which then built up to toxic levels. Tank is recovering now... I think I will start at 10% of recommended doses...
I would encourage u to do as large a water change as is possible... I did 4 50g changes... Water volume is ~220g

Are you carbon dosing at all. I almost wiped my tank with a nopox overdose and experienced losses in the same manner you describe.
