Why Is My Alocasia Browning at the Tips?
Brown crispy leaf tips are the houseplant world’s most common cosmetic complaint — and usually have nothing to do with watering.
Three real causes: low humidity, fluoride/chlorine in tap water, or salt buildup from fertilizer. Soil moisture is rarely the answer.

Three things to check, in order
Low humidity
Tropical species evolved in 60%+ humidity. Indoor air in winter often drops below 30%, drying leaf tips before the plant can compensate.
Fix: Run a humidifier. Group humidity-loving species together. Pebble trays underneath pots help slightly.

Tap water sensitivity
Calatheas, prayer plants, dracaenas, and spider plants are sensitive to fluoride and chlorine in municipal water.
Fix: Switch to filtered, distilled, or rainwater. Or let tap water sit uncovered overnight to let chlorine evaporate (doesn’t help with fluoride).

Salt buildup from fertilizer
Excess fertilizer salts accumulate in the soil and burn leaf tips. White crust on soil or pot rim confirms this.
Fix: Flush soil with clear water every 3–6 months. Pour 2–3x the pot volume of water through and let drain fully.
