I boght a nepenthes from a greenhose in Feb. I nursed it back to health and it's starting to pitcher. I still don't know what kind it is. One of it's new leaves is has turned reddish brown. I don't have alot of experience with nepenthes I only have four. One N.bical, two N.ventrata's and the one I bought from the green house. It gets indirect sunlight most of the day and direct sun for about two hours in the afternoon. I also have a grow light over it. The leaf was toward the window so I think it may be getting to much sun. I turned the plant so that that leaf is now away from the window. Is this something I should worry about?
