plate coral dying?

Im just wonder what's going on with my plate coral. My water parameters are
good.78F,1.024,ph 8.3, cal 410 PPM,alk 9 Dkh. The only thing I changed was my lighting last night. From T5's to a diy led lighting system. I have dimmers on my leds and I have
adjusted them close to same lumens as my T5 and slowly plan to acclimate the coral to the light.
Alll my other coral are fine. I did notice the plates coral mouth open and something black coming out of it.

T5 or T5HO?

T5's and upgrading to LEDs would be a huge change!

Lumens is not the same as PAR... how big is this tank?? how many'what kind of LEDs do you have?? My guess would be you dimmed the LEDs too much and there is not enough PAR reaching the coral, resulting in a lack of light.
