Looks like tissue die off. What are your parameters right now?

I thought it looked like black band disease but I've never seen it before, just from searching on google.

Possibly LED hot spots that have killed spots and that's just algae growing on the skeleton

Turn the leds off and see if the problem goes away over time. Or if its gets worse.

Leds without a diffuser will point directly on one spot

Not to that extreme:) They aren’t lasers...

Plenty of people run leds. This would be a well know problem if leds were the cause.

This looks like stn and algae growing in place.
