Sps losing colors a few weeks after adding

What are some signs of high salinity?

Unhappy corals...losing color, shrinking, shriveled, retracting...listen to your corals, they tell you when they're unhappy...

All lps look amazing, even better than anyone else's that i have physically seen. My torches, euphyllias in general, duncan etc look amazing, puffed up and healthy. Maybe slow growth for lps. Softies look very good as well. Only *some* zoas, acros and some other sps arent doing so well, slow growth, most of them lost color, most have polyps retracted

Update
So after dosing the reef colors abcd from red sea, I can see some of my corals may be better now, but very slightly, zoas look happier i think so i will continue dosing. I think i found the reason to my problem (thanks to all of you :) ) my refractometer was not showing me the correct salinity. It was saying that its 34 ppm (1.025) when in reality it was about 41 ppm (1.030) yikes ! Im not sure that its that high yet, will try and get calibration fluid instead of using reference substance from a calcium test for calibrating the refractometer. Either way its too high but the thing that i dont understand is why my lps, including torches, look so healthy and so well (except for the one in the photo) hmm... Ill update after i get the water to the right salinity and if i see any changes. Cheers!

I had this exact issue when starting out, my problem turned out to be my salt level. The refractometer I was using was incorrect and my level was right at 31 I invested in like 4 different ways to verify salt and brought it back slowly. The Milwaukee is my go to now

Why did you used a calcium reference solution to calibrate the refractometer?

Did your corals color up a lot and extended their polyps? And also did they grow faster? How were your lps and softies before and how are they now?

It says on the reference substance that it has 33ppm salinity
