Hello, can anybody tell me what's going on with my discosomas?

I am keeping them in my tank since months without any problem. They always grew fine and wednesday were like this:

However since saturday they are like this:

Thing is: I have several colonies and they all look the same, quite contracted. All other corals (soft and LPS) are ok. No recent technique changes to the tank. I just added a quadricolor 10 days ago, might it be disturbing the discosomas by releasing some compounds?

Otherwise:
50 liters
60w led light
total of 3000 l/h of flow

Values are very low: NO3 1mg/l and PO4 0mg/l

Thanks in advance for your help.

Have you checked your alkalinity? Mushrooms can start tanking pretty quickly if it's too low or unstable, they usually look like that then start detaching from the rocks.
