Can someone diagnose my plants for me?
Growing in a 50 gal terrarium under 3 ft T10 lights about a foot away. Other Nepenthes growing strong right next to these with seemingly no side effects.
I first thought pests, but generally the damage is much more irregular with bugs.
My second though was burning from the light, but I've had Nepenthes grown in close to full sun before - not the correct color for burned leaves.
My final prognosis was humidity related damage? Anybody seen similar things on their plants and then had them survive?
The affected plants are N. tangalensis and N. lowii - neither are pitchering (at least not more than a couple of millimeters before popping the lid).
