⚠️ Hard Water Alert
High calcium and magnesium levels can accumulate in potting soil over time, causing brown leaf tips and nutrient lockout in sensitive species.
Recommended Actions
- • Use filtered or distilled water for Calathea, Ferns, and Orchids
- • Flush soil with distilled water monthly to prevent salt buildup
- • Consider an under-sink RO system for large collections
- • Repot annually with fresh soil for sensitive plants
