Peace Lily Yellowing: Light, Water, and pH Solutions

Alfredo's 6-month-old peace lily has persistent yellow/brown leaf tips despite no fertilizing and watering only when slightly droopy. Leaves are pale green, suggesting pH issue.

Multiple Contributing Factors

Watering timing: Water before leaves wilt. Slight droop means you're slightly underwatering.

Pot size: Photo suggests very small pot with surface roots exposed—contributes to stress.

Light: Needs lots of bright indirect light. May not be getting enough.

Temperature: Above 80°F causes leaf discoloration.

pH/nutrient uptake: Pale green leaves indicate high soil pH (>6.8) or hard water. Nutrients become insoluble.

Corrective Actions

1. Trim discolored leaves as they appear.
2. Water when top inch of soil is dry—not at wilt point.
3. Ensure bright indirect light.
4. Test soil pH; acidify with sulfur/sulfates if >6.8.
5. Use filtered/distilled water if tap water is hard.
6. New growth will green up after pH correction; old leaves won't recover.
