I have similar issue, sps (acropora) STN from the tip after 2 weeks in the tank Montipora will brown out and die LPS are doing fine , DKH ~8-7.5 No3 ~10 p04 ~ 0.08 and tank been running over few years. test and found out par is too low(~150 par) under 6 bulbs ATI T5(all the sps are at the bottom of the tank)
Low par caused my sps to STN from the tips..
The reasons I know it the light , because I low my T5 to get above 200 par nothing else is changed . buy some test sps it doing fine got good PE and grow
Par meter is your best friend if you going keep sps .if water parameters is in check
