If deficiencies in nitrogen or phosphate occur it can throw the balance for controlled growth off; more so it seems when higher alk encourages faster calcification.
FWIW I have been dosing vodka and vinegar for over 8 years in a a heavily fed mixed reef system with a majority of sps. PO4 holds between .02 to .04 ppm with NO3 under 1ppm. alk in the 8 to 10 dkh range doesn't occasion burnt tips or other stn in my case.
Once in a while a very small of sodium nitrate offsets any potential nitrogen deficiency.

If I remember correctly, you are dosing vinegar/vodka at 70/30? How many ml/gallon are you dosing? Thanks
