Nepenthes rajah × mira: Color Changes and Care Adjustments

A Nepenthes rajah × mira hybrid showed unusual leaf coloration after a location change. Both parent species are ultra-highland, requiring cool, consistent temperatures (65–75°F day, 55–65°F night) and high humidity. The grower's 72–74°F day/69°F night under CFLs may be too warm and dry.

Recommendations: try weak foliar feeding with seaweed-based fertilizer (Maxsea, Seagrow) for trace nutrients. Consider switching to LED lighting for cooler, brighter conditions mimicking mountain habitats. Monitor for improvement.
