Digitata loosing flesh

[newsalt]

I have an orange digitata that I've had for years. Lately, I've noticed some (not all) branches are loosing patches of flesh. All my other corals are looking great. What could be the cause? I dose the following daily:

4ml Vodka
4ml Zeo Phol's Xtra
8 drops Zeo Coral Vitalizer
8 drops Zeo Sponge Power

Thanks

Is the flesh just peeling off? Type in RTN or STN (rapid or slow tissue necrosis)

Seems like it's just peeling off. In this photos, the areas that are green is where it's missing flesh.
