Lps plating coral going brown on the edge

[Jasongtr]

This is a graffiti war coral, bit blurry picture as top down.

On the right hand edge it's gone brown where it was fully coloured as the rest of it, what causes this?

If it were too much light I'd expect the top to go where it's most exposed to the lights, would lack of flow be doing it?

If I moved it would it recover I guess is the next question

Thanks

Lots of plating corals will retract from an edge if they are recently moved and getting too much light? They will do the same if the edge was bumped or if another coral is reaching out and attacking that end?

None of that applies though, the light would hit the top harder than the side that's gone brown, it's not been moved since it was put there a couple of months ago and there's oy one frag within 6 inches of it and that's another war coral

You do know why they call these "War" corals? Check it at night.

Check what, there's nothing near either of them and they can stay together
