its totally normal for corals to turn brown or sometimes white where the sun don't shine. if I am not mistaken I see a pretty distinctive white patch on a branch that should probably be receiving enough light. If this is the case Id just get an icp-test and ensure no metals are build up, then look into flow and food. If the tank has not had any large back to back waterchanges in awhile sometimes doing 3-4 consecutive 25% waterchanges really helps get the tank setup for the year. I started doing icp test every 3 months and it really helps me keep the tank stable as the frags become colonies.

Orphek? Suspect. Tell me more about your lighting, how many units, lighting schedule, height off water, how long running, any other lighting to supplement, what lighting did u run prior to orphek

Im speaking with very relevant experience and question the orphek, im running two V4 compacts plus 4 x54w t5s. I know the issue you are dealing with first hand...
