Firework Clove Polyps white and wilty?

[One Reefing Boi]

Not sure on this one. My clove has been going strong for about 2 months now. Not super fast grower but not slow either. Suddenly (last few days) two of the cloves have kind of gone pale and shriveled up.
Lighting is the same, haven’t moved them since going in, and the other heads all seem happy. Any thoughts? In the pics it’s the two on the bottom/left

I have another clove polyp happy as a clam and the only thing I added was a frag rack but it’s one foraquariums and had great reviews and all my other corals are happy.
