Green Torch Coral turning white?

I wonder why two heads of my 6 headed torch coral are turning white. It's tentacles are nice and thick, it is not showing its mouths. It has been in the same spot for say 7 months. I wounder if the halides are bleaching it?

sounds like it, are they new bulbs? How high up is it?

The weird thing is that the entire thing is not bleaching. The pod in the very center and at the very bottom are the only ones turning white. They have been in the same place for almost a year now with no problems.
