Diagnosing a Declining Nepenthes burbidgeae × platychila in Texas

Heather's prized N. burbidgeae × platychila declined after developing rust spots (treated only with neem oil), then produced a deformed leaf with an uncertain growth tip. The plant grew under a tree in shade, was recently repotted into sphagnum/perlite, and moved to a south-facing entryway. She's in Texas, growing outdoors.

Likely Culprits: Light, Temperature, Humidity

Highland Nepenthes need bright light—shade under a tree is often insufficient. They also require warm days (78–85°F) with night drops of at least 15°F, plus high humidity. The recent repot and relocation add transplant stress. Without knowing exact water source, temps, and humidity, the expert suspects inadequate light is a primary factor.
