Sagging/ droopy hammer?

[LostNemo]

Had this hammers for awhile now like 2 months. But recently noticed the past 2 weeks it’s been sagging a little. Does this mean is trying to split and branch? Or is this sign of something else. All my other corals are doing fine.

Did you ever figure out what was causing it?
