Green Slimer Tip issue

On Sunday October 4th I noticed one of the tips on my green Slimer was looking odd. It’s purple and the tissue seems to be wrinkled. There was a Xenia next to it that I removed thinking this might be the issue. But today I noticed some more tips doing the same thing but on the opposite side of the coral. Today was water change day so I tested numbers. The Alk has changed over the last 4 weeks. 9/19: 8.6, 9/27&10/3: 8.9, 10/10: 8/15. During the last 3 weeks I noticed that it has either slowed or stopped growing. All other corals are doing great. Lights are AI Vega with blues at 78 and white at 65(This is 4 hours in the middle of the light period and is between 200-250Par at the Slimer) the other 4 hours is at 78 blues and 35 white.

Salinity: 35ppt
Alk: 8.15
Ca: 450
Mag: 1380
Po4: below .1
No3: Below 10
Temp: 78
Ph:8.3
