Symptoms to look for in Pepper
Yellowing usually starts on lower, older leaves and moves upward if the cause persists, sometimes with a mottled pattern if viral.
Common causes in Pepper
Most commonly a nutrient deficiency once fruiting heavily (peppers switch to needing high potassium once flowering) or inconsistent watering; a distinct mottled pattern instead suggests mosaic virus.
How to diagnose yellow leaves in Pepper
Check soil moisture first. Wet soil + yellow lower leaves = overwatering. Dry soil = underwatering. Yellowing between veins = nutrient deficiency.
How to treat yellow leaves in Pepper
Switch to a high-potassium feed once flowering begins, and ensure watering is consistent. If yellowing is mottled rather than solid, the plant likely has a viral infection and should be removed.
