Definitely happened to me and it was too much light in my part.

well my hammers are close to the bottom and i'm using Reefbreeders Photon V2's LED lighting. It comes with 6 channels. I don't even use the reds and the greens and the royal Blues at their highest intensity in middle of the day is only 50% with whites only at 20% in a 2 ft deep tank. Doubt the lighting is to intense but maybe it is i don't know. The only other place in the tank that would be less intense is if i put them in the shade.

All of my other 32 corals in the tank are just fine with great color. confused i guess.

I've had a couple that didn't like leds and lightened up and only got darker under an over hang.
