Troubleshooting Slow-Growing N. jamban: Superthrive May Be the Culprit

An N. jamban in a highland terrarium (80°F day/55-60°F night, 60-80% humidity, 15-hour photoperiod) grows slowly with small, deformed leaves despite pitchering. The grower uses monthly Superthrive foliar spray. Jeff Dallas suspects Superthrive's rooting hormone is disrupting leaf growth when applied to foliage. He recommends stopping Superthrive and switching to a weak foliar fertilizer (e.g., ¼-strength Grow-More orchid fertilizer for Phalaenopsis) every two weeks. Conditions are otherwise excellent.

Good Growing!
