Brown, crispy edges on leaves. May progress inward.
Often caused by salt buildup from fertilizer or mineral buildup from tap water.

Stress from environmental changes, temperature fluctuations, or underwatering.
Keep plant in consistent conditions. Protect from cold drafts. Maintain regular watering schedule. Be patient - it may recover.
Plant not growing or growing very slowly.
Insufficient light, wrong temperature, nutrient deficiency, or pot-bound roots.
Move to brighter location. Ensure temps are 60-85°F. Fertilize during growing season. Repot if roots are crowded.
Small insects on leaves, sticky residue, distorted growth, webbing.
Common pests include spider mites, mealybugs, scale, and thrips.
