Hammers looking wilted and recessed

[1Bigfish]

Hello reefers!
I have 3 hammer and now 1 frog looking wilted not as puffy and expanded as usual. I hope some of you will be able to help me out with what may be going on. Tank is a euphyllia dominant tank with a few zoas and acans.
parameters
Salt 35
Ph 8.05
Temp 78
Alk 9.2
Magnesium 1320
Calcium 380
Nitrate 5
Phosphate.01
I am dosing ATI Essentials pro and wondering about the low calcium having something to do with the problem and the best way to fix this. Any help is appreciated!
Sorry about the blue pics.

i'm more concerned about the .01 phosphates. lps generally like a few nutrients in the tank. .03-.ppm1 phosphates and 5-10ppm nitrates.

Hmmm....that could be the problem.You think I should turn the skimmer off or only run it half the day to try and leave some nutrients in the water? Any suggestions? Thanks
