Nepenthes ventricosa × boschiana Pitcher Die-Back: Natural Growth Pattern or Problem?

A grower's hybrid Nepenthes shows pitchers browning from the lid downward, though the plant produces new growth. After providing detailed conditions (5–6 hrs light, 30–60% humidity, 80s°F day/50s°F night, distilled water, 75% LFS/15% perlite/10% bark), the expert concludes it's likely a natural growth phase transition – older pitchers die as the plant prepares to vine and produce upper pitchers. Since new pitchers form and develop well, and a companion N. ventrata thrives in identical conditions, no environmental issue is indicated. Monitor new pitchers; if they mature normally, the plant is healthy.
