I recently got my AC vents sealed, so there's no sweating coming from them. However, I've noticed grey dots or what looks like spores appearing on my ceiling, further away from the vents. Is there anything else I can do to prevent more of these from popping up?

Those grey dots could potentially be mold, which is definitely something to be cautious about. It's crucial to address it before it spreads. Have you considered checking for adequate insulation in the attic? That could help prevent further moisture buildup and reduce the chances of mold developing.
It sounds like there might be some issues with insulation above those spots. If there's attic space above, inadequate insulation can lead to moisture issues that promote mold growth. Blown-in insulation is decent for insulation value, but it doesn’t provide the same moisture barrier as traditional batting, especially if it’s not evenly spread out. You might want to take a look at what’s happening in your attic above those spots.
