Help! SPS tips dying

The past couple days I have noticed on about half of my SPS the tips are turning white... like flesh falling off white, not bleaching. I am not sure what is causing this??? My alk has been stable.



Alk... anywhere from 8.7 to 9. Once it gets down to 8.7 I bring it back up to 9 over the course of 2 days using baking soda/RODI solution.

Cal - steady around 470

Mag - steady around 1360

Nitrates - pretty much undetectable

Phosphates - ? I use GFO and there is hardly any algae in my tank so I am guessing it is not an issue.



I am lost. My alk seems fine, so what else could it be?



I use RODI and dose a gallon of a kalk solution overnight each night. On a drip that takes about 5-6 hours to empty the gallon jug.
