Is my red planet starting rtn

[Betex]

Coral has been in tank for over a month, polyps nicely extended and branching but I just noticed this speckle of white at the bottom right and before I glue/cut it off just wanted to get an idea if this is rtn or just more of a shaded area than the rest.
Thanks!

I tried to zoom in, you can see the line of the base flesh below it, possible sting damage or something chewed it?

my pc pro rainbow had something similar to that. After doing some testing found my Cal was way low. May want to do some testing to see whats going on. Also after fixing the CAL problem the coral still has the same spot, but it is not getting bigger.

White light pic? Does ot still have polyps in that location? May just be shading.

It does on the branch not the white part. It is a shaded are where that branch is but just wanted to make sure.

I'd keep an eye on it. Does it look like fresh skeleton?
