Very Common

Whiteflies

Small, white-winged insects congregate on the undersides of pepper leaves and excrete honeydew. This sticky residue can eventually develop a black 'sooty mold' or appear as a fine white dust/speckling.

Common

Mineral/Salt Deposits

Evaporation of hard water or excessive fertilizer runoff can leave a white, crusty residue on the leaf surfaces or soil surface.

Common

lightbulb

How to confirm: Wipe a leaf with a damp cloth; if the white substance disappears completely, it is likely mineral buildup rather than a pathogen.

1 Flush the soil thoroughly with distilled or rainwater to leach out accumulated mineral salts and prevent further buildup.

2 Wipe the leaf surfaces gently with a damp cloth to remove the crusty residue and prevent it from clogging plant pores.

3 Switch to using a balanced liquid fertilizer and monitor moisture levels with a meter to avoid over-fertilizing.
