Help my torch.

Two days ago I bumped my torch while cleaning a broke two heads off. I used a pair of my coral tongs to move it a bit so it looked better in the tank shape wise. The last two days I’ve lost three heads around the area I grabbed by. I would suspect that I damaged the polyps but they look brown which scares me about the whole brown slime disease. Never dealt with that so just wanted to get someone that’s more knowledge to take a look and guide me on my next steps. Thanks in advance.
