Nepenthesis
Formerly known as Pineapple
IDK what it is doing, it like won't pitcher and now the first two leaves are turning black/yellow as you can see in the pics. I recently removed my shade cloth, so maybe it is sunburn? I doubt it though because no other plants had issues with it. All other leaves are fine, just two new ones -- and it won't pitcher with 55F nights, 70F days and high humidity in a greenhouse.
