Looks like some serious bleaching. GSP can usually withstand some really high PAR though. I’m not familiar with this light but do you know what intensity you have them at? Do you have a PAR meter? Also check your temperature. Could be too high.

Edit: After looking at the pictures again it seems odd that it’s only some of the coral in similar locations of the tank. The last picture looks like the mushroom is even in a shaded area. Something is making them expel their zooxanthellae.

Reproduction is sometimes a stress response.
Can you think of anything else thats changed?
Check your temperature and ph.
Corals in the ocean are beaching because the water is getting warmer and more acidic from atmospheric co2.
