I’m not sure, because its open in the day but I saw something similar on my other hammer coral then it went away. It might be a stress factor? I’m not too sure but I’ve been dosing phos a lot lately because I’ve been dealing with bottomed out phosin your first image, the darker brown tentacles on the left center edge are the classic brown jelly color, but the overall presentation doesn’t look like BJD.
BJD looks like brown rotten yogurt or cottage cheese laying on top of the dying coral flesh.
The puffy inflated flesh is interesting, and possibly worrisome but not looking like brown dirty yogurt, at least not yet.
The problem with BJD is that when it happens, it quickly kills the head as it covers the dead body with brown sloughing flesh, often causing mortality in a day.
But this appears to be something else?
I fed right when my blue lights went away, so probably 30 minutes after, very likely it can be from that because I remember my gold hammer did similar things after I gave it mysis shrimpHow long after feeding did you see this? I’ve seen it on my torch a couple times after broadcast feeding.
These are currently my parameters, very out of wackCan you tell us the essentials about the tank this is in and how its maintained? Also we'd like to see all water test results you have.
I am trying to raise my phosphates, I just dosed 0.15 ppm yesterday and it went back down to 0 in a day because I’m dealing with dinoflag as well

I’d say your alkalinity is a little low too. I’d recommend at least 7-7.5, and calcium at least 400-420 if you have torches.
They generally like more nutrients in the water too. Try to keep phosphates at least 0.04-0.05.
Try to keep magnesium around 1400 as well. My experience with Euphyllia is that they like magnesium running a little higher (I keep mine at 1450).
It's fine to dose higher to avoid it coming back down to zero again.
How is your salinity? Could be that your ca, alk and mg numbers make sense for the salinity level of the tank.Can I just dose alkalinity and calcium or do I need to raise mag first?
For the mineral levels I'd just do some water changes.
For the nutrient levels, add NO3 and PO4 to your new saltwater before it goes into the tank.....dose to your target levels for each. That way nutrient levels don't go down in the tank and you get the needed boost for the mineral parameters. An enhanced salt like Reef Crystals would be nice, but even "plain" salt like Instant Ocean will help.
Thats a really good idea to dose the water change water. Right now Im usint instant oceanFor the mineral levels I'd just do some water changes.
