Concerned about these hammer corals

These are newly purchased hammer corals, they've been in my 12 gallon fluval edge nano tank for about a week. I added them the same day I added the torch in the foreground.

Yesterday they only extended about a half inch but today I'm not even getting that.

I've got zoas, candy cane coral etc that all seem to be doing great. Water parameters are:

salinity: 1.026
ammonia: 0
nitrite: 0
nitrate: somewhere between 10-20 (api chart sucks to read)

Could too much light cause this? I do have them under a Kessil 150.

Photos attached, here is a video as well:
