Whiite/light areas on a encrusting type coral

[JAWSIII]

Hi all. I got this coral about 2 months ago. I am not even sure the name. I was told it is an encrusting coral and like higher par. I have it secured roughly 8 inches below the water surface at the top of my rock scape. I am using a radion xr15 mounted 8 inches off the water surface. I rented a par meter and the par that this coral is receiving is 325 at the brightest light of the day which runs about 5 hours.
Water params as of yesterday are

Alk 10.0
Calcium 460
Ph 8.1
Mag 1400
Temp 79
Salinity 1.026
Nitrate 5-10
Phosphate 0.02

I noticed a few days ago that there seem to be some whiter or lighter areas beginning to form at different spots on the coral. It is a reddish orange color overall but these lighter spots look more blueish white.

is this too much Par for this type or is this growth? I got the best pics I could.

Hi!
Looks like you have a nice encrusting rainbow montipora.
I wouldnt worry about the body color too much unless you see the polyps retracting and dying or the flesh start deteriorating.
Some like lower light but can absolutely be acclaimated to higher par like this.
