[Chipp]

i bought this in december and since then it has only encrusted the left side of the plug, but the last few days the tip started to turn from green to light purple and now white.

I know my ph has always been low it dips down to 7.6 at night. Other corals seem fine, but are growing slow. The only thing i have changed was that a couple of weeks ago i adde a fuge with just live rock, cheato and pods. Imhave been adding ocean magik plankton as per the directions. I dose 3ml of alk and 5 ml calcium per day.

Whoops i meant i add 30ml of alk and 29 ml calcium per day.

Levels look decent.
What I see that may be hurting you is a huge amount of Cyano bacteria and likely high phosphates. Additionally, what is your water flow as these corals require moderate to strong flow and your salinity is a tad low. Bump to 1.026

My phosphate tests at 0 (salifert). The maroon color isn’t cyano. it doesn’t come off if i rub it or scratch it with my fingernail or a brush. Aquarium is 90 gallon with two vortech mp40 running at high points of 65%. Return is less that 800 gph, probably 400-500. That coral is about 8 inches from the vortech.

Cut off the white part. Its there's sometime bad on it, you don't want it spreading.
