2 SPS being weird

[Klag]

I have quite a few acros doing well, from Maricukture to a Walt Disney. 2 of my frags are getting some white spots and I don’t know why. 1 is a TSA daydream and the other is some mariculture. Any advice or input is welcome

Tested a few days ago, just got home from work.
Nitrates: ~3
Phosphates: ~ 0.08
Alk: ~8.5

A picture is a thousand words.
A picture in white light is a million words.

How long has the tank been set up? What kind of lighting and flow? Not saying it is the issue, but I would personally raise Nitrates a bit. Outside of saying your parameters are good it is very difficult to identify SPS issues sometimes but I would start there.
