Montipora lights spots and circles?

[___]

I'm new, need some advice please.
I have a new monti. He looks good, pretty pink with green circles.
Recently some of the edges have gotten lighter in color and the biggest spot has little white circles. Is this good? Bad?
I'm attaching a pic, had to enhance as much as possible, but it's still really hard to see because the frag is in the middle of the tank.
Appreciate any guidance.
Thank you!

Edges are normal. Moderate light and water flow.
Not an ideal first coral. Assure parameters are acceptable especially salinity, ph, mag, alk and calcium

Thank you.... Not my first coral, just first Monti.
