Too much or not enough light?

[slogan315]

Also, how long are you guys running your lights for?

7am-9pm on kessil
10am-6pm on t5

10am-6pm is the only substantial photo period. The 3 hours before and after are very blue sunrise/sunset for me.

Hmm, do you know how many inches above the water surface, also do you know what the PAR is in the middle/bottom of the tank and the intensity of the lights?
By the way thanks for the help

No sry in par. About 8-9” of water w mount. Redsea 90s. Both channels blue and white at 100% so it’s was like 15k I guess. I did not use any spectrometer ai pls Kay an anecdotal guess. 10 hour photo period. U can guess what these are and how they are working out I think those lights and know they grow coral. Good luck bro

UPDATE:

Thanks everyone for your help, especially @slogan315 and @HudsonReefer2.0. This is what he looks like today
Hard to tell in the photo but it has great polyp extension and the white patches are not growing (not to jinx it but it appears they're healing) thanks again @slogan315, he is a wild piece so he is probably getting situated, my phos was also really high so I added some removal media to help with that. Anyway I also turned down the light schedule to 9 hours instead of 11 hours, which could have also been the issue. Thank you all again for your help.
