Mind Trick Monti Went All Purple

[T-J]

My frag of Mind Trick monti has color shifted. Instead of having the green center with purple growth edge, it is now all completely purple. Any ideas if it's an indication of too much or too little light?
Thanks!

May be too much light. It uses zooxanthelle for color and too much light may cause color shift

Could be color or type of light. Could you tell us about your lighting?

I'm running a 50" ReefBreeders with two Lumenbars (HO UV and Royal Ice). Not running red/green channels. Blues are set to 55% and white is 15%. The mind trick is getting 260 PAR.

Here's the PAR map for the latest settings. (note, not a current pic of tank, just a "clean slate" pic I use for PAR maps)
