Help With Scolymia

I've noticed that my scolymia has had some of it's tissue recede as you can see in the picture provided. I'm trying to keep an eye on the amount it has receded which is not very much, very slow in fact but i'm not sure what it could be. I've had this bleeding apple for roughly 3 months now and did not notice this when first acquired. I recently changed from an AI Vega Color Led to a Kessil A360we about 2 weeks ago.

My max brightness on my vega was 60% and I started my kessils out at 45% and is currently at 55% as of yesterday. I've seen no bleaching of any sort on any of my corals (SOfties/LPS) in fact I have two other scolymias and a cynarina that are all doing perfect. My water params all seem to be fine,
Calcium 400
Mag 1300
nitrate 0
phos 0.03
Alk 9
PH 8.3

could this just be a flow issue? I'm using a gyre 130 and mp10 in a 50 cube and occasionally it will get some heavy flow depending on what random flow it's on between the two. Outside if seeing some of the skeleton the scoly is doing fine in that it's eating fine and opening up at night with feeding tentacles and puffy during the day as seen in the pic. Any ideas?

OH!! before i forget, I recently placed it on the sandbed after the whole time i've had him being on a piece of PVC that elevated it off the sandbed, when i noticed the tissue pulling away i thought because it's started on the underside then maybe it was the flow pulling it up and off the skeleton. He's been on the sandbed now for the last couple of days. FTR it was seemingly happy on the pvc too in terms of eating and such.

I have all community reef tank mates, couple of dart fish (purple/fire), couple clowns, pajama, yellow goby, yasha and a tailspot blenny. Nothing is touching the coral not even at night, the closest coral is another scoly. I just used an iphone as that is all i have for pics.
 
You might try to elevate your nitrate levels slightly (at least to readable on your kit) and see how it responds
