Brown leaf tips
Caused by fluoride or chlorine toxicity from tap water, low humidity, or salt build-up in the soil; switch to rainwater or distilled water, flush the soil occasionally, and raise ambient humidity.
Mealybugs and scale
White cottony mealybugs or brown scale clusters appear in leaf axils and along the underside of leaves; treat promptly with neem oil or isopropyl alcohol on a cotton bud, as these pests spread rapidly in warm indoor conditions.
