Mineral Deposits (Hard Water)

Calcium and magnesium from tap water can leave a white, crusty residue on the surface of the leaves as the water evaporates.

Common
lightbulb
How to confirm: Observe if the white spots are hard, crusty, and do not move or spread across the plant tissue.

1 Gently wipe the leaves with a soft, damp cloth or a cotton swab dipped in distilled water to remove the crusty mineral buildup.
2 Switch to using distilled water, rainwater, or filtered water for future watering to prevent new calcium and magnesium deposits from forming.
3 Monitor the soil moisture levels to ensure you are not overwatering, which can exacerbate mineral accumulation on the plant surface.
