Are 'wiggles' along leaves just normal for some Nepenthes? Most that grow out have a nice smooth, broad shape along the entire leaf. Yet some are just ridiculous. Best example, my Red Dragon. This thing always looks like I'm growing it in some type of wind vortex or something crazy.
I have a few others that do this too, sometimes spectabilis and miranda. Both of those will somewhat flatten out over time though. But mainly, I just want to make sure these plants aren't struggling with something, such as temperatures that cause this shape to happen.
