Mineral Deposits (Hard Water)

Calcium or magnesium from tap water can leave white, crusty residue on the leaves after evaporation. This is not a biological pathogen but appears as a dry, white film.

Common

lightbulb

How to confirm: Try wiping a leaf with distilled water; if the residue dissolves easily, it is likely mineral buildup.

1 Gently wipe the leaves with a soft, damp cloth using distilled or rainwater to remove the mineral crust without damaging the plant's farina coating.

2 Switch to using filtered, distilled, or rainwater for future watering to prevent new calcium and magnesium buildup.

3 Monitor soil moisture levels to ensure you are not overwatering, which can exacerbate mineral accumulation in the substrate.

Edema (Cellular Rupture)

Common
