The soil is molding. It could mean that your plant isn’t getting enough light to absorb the water in the soil between waterings

Try using sone hydrogen peroxide in your water. Maybe 2-4 TBSP per gallon. It will keep your roots healthy.

looks more like mineral build up than mold. this comes from hard water and can be remedied by flushing the soil with rainwater or distilled water
