Monti regained colour only on the edge/new growth

[entranced]

So a while back i had issues with temps, etc.
My acros and some montipora went white but once i settled the parameters the acros quicly regained all their color everywhere.

But i have a chili pepper monti that looks dull except on the edges where the new growth is.
Then i have the fingertips green monti that doesn't look as green as it used to. The colour it regained is noticeable but barely after one month of the incident.

Is it fixable or they'll be like that forever?

How long is a while back the others looked better?
IMO, some take longer than others.

Looks just like mine. I believe it's a slime.

Monti and digi in my tank are very sensitive to anything that’s out of wack in my tank. Once it’s bleach I can never het it to color back up except the new growth. I just cut the new growth and glue it back to the rock and trash the bleach part.
