Why is my Kenya tree falling

[Vcntv]

I'll reiterate a full tank shot and add a list of the other corals and how they look. Regarding PO4 .2 mg/l isn't going to be an issue for it. Nitrates @ 50 mg/l is high and needs to come down but Kenya tree should tolerate that level. Alkalinity should be raised, I wouldn't consider 6.1 to be an issue in a mature system that would have stuff generating alkalinity but, and correct me if I'm wrong, it looks to me like your system was set up with just maybe bacteeria and not with maricultured or wild live rock.

I used 3 live rocks 20 pounds of tbs rocks here’s an update on the coral. I put the rocks in a few weeks after my cycle completed which I started with Dry rock and Fritz bacteria

Great to see some maricultured rock in there. Dry rock or "live" rock that has only bacteria added to it lacks many organisms that are essential for a reef ecosystem. (Only a few percent of the microbial stuff on reefs can be cultured and stuck in a bottle.) You didn't mention any other corals is htis the only one you've added? Patience is definitely an asset.
