Yellowing Nepenthes ventricosa: Normal Color or Problem?

A grower's 3-month-old N. ventricosa shows yellowing from bottom up, including new leaves, under 16-hour lights at 40% humidity.

Diagnosis: Normal Appearance

• Yellowish-green is typical for healthy N. ventricosa
• Dark green often indicates low light + over-fertilization
• Red pitchers on mature plants confirm good health

One Genuine Concern: Soil Mix

• Peat/perlite is too dense for Nepenthes
• Preferred: Coarse mix with bark, coconut chips, long-fiber sphagnum
• Goal: Rapid drainage, high aeration
• Action: Repot into appropriate Nepenthes mix

Current Conditions Assessment

• Light: 16 hours artificial — good
• Humidity: 40% — acceptable for this species
• Watering: Not specified — ensure not waterlogged

Bottom Line

Plant is healthy. Repot into coarse, well-draining media for long-term vigor.
