More than likely its due to the weather change, air flow of your room and the top of the soil staying moist.

I switched to bottom watering only in the cooler months and its helped curb the mold on most of my plants.

This is common with Miracle Gro potting mix. Some nurseries bake out their potting soil. That’s the only way to clear out insects, mold, fungus and seeds. Mold won’t harm your plant. It lives on wet soil. Let the soil dry out more between watering. Baking soda mixed with water can help clear it or use a fungicide.

If it’s the “yellow dog vommit” version, it’s unsightly but actually good for the soil from what I’ve found. Agree with above, let it dry out and try bottom watering for winter I just bought some Arden (I think) fungicide on sale at Fred Meyer, as we tend to get many mold/mildew problems up here with lack of airflow
