Sick Acropora?

[Pado]

Good morning, I have a problem with an acropora, and only her at the moment, everything else is perfect. In the morning, when the light turns on, I find it full of these white "things". I have no idea what it is, it lost a tip at the beginning, but now it seems not to lose any more tissue, or very slowly. She has had them for a week, as soon as the light turns on, in about half an hour, they disappear. What could it be? I hope for your knowledge, I don't know how to intervene.

Flat worms?

Need a better photo, white light.

Looks like it might be trying to spawn? Could be a slime coat due to a stress reaction but usually that’s more stringy. Is anything living in it/bumping it?

The more I look, the more I see flatworms/pest.

Can do photos just in the morning at 6.30am (Rome time zone, so i'll do them tomorrow) when the lights turns on, after 10 minutes of turning on the lights, everything disappears. They are white, totally white.
