Cabbage leather rotting??

[JoshKC]

I've had this green cabbage for about 6 months. No issues till recently. It appears that it is rotting for some reason. My water test fairly well and everybody else in the tank is happy.
Setup- Reefer 250, (2) Kessils, BML actinic, Kalk reactor, bio reactor, calcium reactor, carbon reactor, Reef Octopus 250 skimmer, HOB refugium.
Water- 1.026, calc.- 540, alk.-10.64dhk, ph-7.76, phos.-.01, nitr.-0, ammo.-.1
Any ideas on what you can tell from these pictures, ideas, opinions welcome

I wouldn't worry too much. pretty tough corals. what other coral in the tank? that's a lot of calcium for softies. I have a tank full of softies and a few lps and I don't dose anything. calc is about 380 with wc's.

Yea, my calcium is thru the roof it seems, but when I initiated this thing I didn't want to limit what I could put in the system as far as livestock goes. Well, Ive lost a few. Now Ive got a RBT anemone, Duncan, Hammer, a pitiful Torch, Harry Shrooms, Zoas, 2 Skunk Cleaner Shrimp, pair of clowns, Scarlet Hawk. Oh yea, a Chalice. Im gunna try my hand with a Montipora and if it does well Im done, or so I tell myself
