Well, without a picture it's impossible to say. It would also be helpful to know what your nitrates are, but having zero phosphates is never good, either.

Are other corals in your tank doing ok? Anything change lately? Did you checked for rusty pump and power heads....torch bailed out could be parameters not in check, toxic metals in the water, pests, light and flow ....
