Weird smooth skin on milli

[MelReefer]

So I have had a jf solar flare frag for a couple weeks now. It’s doing alright and has some pe but there is this weird patch in the back where it’s just smooth skin. What does this mean?
Front

back

Sorry for bad cell pics. I also feel like the coral is not doing all that well in general. Not as much pe as I would like. Btw the coral came with the smooth skin

My ASD Rainbow Milli does this sometime with the branches that are facing away from the light. Most of the entire back side just smooth skeleton. It’s sort of cool looking.

Ha Np. Yeah here is an example. These two branches were at the very bottom of the colony against the rocks. Lol crazy looking. Is this similar to what you got?
