What are some of the factors that could cause 1 head of a torch to go from this to that in a few days? Salinity, temp, testing all done regularly with Hanna checkers. Not dosing anything. The only thing to note would be that nitrates bottomed out last week so I am now dosing nitrates. Was at 1.0 yesterday.
One other thing I have seen is that around noon or 1pm every day, mostly all of my LPS shrink or retract if that’s the right word. (Shown in pic 3).
Would love any help or suggestions on what may have caused it. Noticed no changes to the coral itself (was looking for BJD) but just a gradual decline of health.

! It has been a battle. Got the phosphate back around 0.5, but still working on nitrate. The nitrate dosing is helping.
