Cut or leave receding tip?

[Chrille26]

Hi! I got this Pistillata in my tank, and I noticed this morning that one tip appears to be receding.
All my other corals look healthy and happy, including Acros, Montis and a mix of lps and soft corals.

how would you deal with it, let it be and see, cut tip or try to glue it over?
Thanks for any advice!

Bump I'm curious as well

It has worsened a little bit since this morning but not alot, I am wondering if it is bleaching or tissue death? I think it is bleaching at this point since I cant see any loose tissue, it just looks like the tissue on the tip is dark coloured.
Any ideas or thoughts are appreciated!

It’s not bleaching it’s stn. It’s getting darker because algae is starting to take over. You need to cut the tip and it will regrow.
