So I recently outgrew my first shelf on the grow rack, and have about half my nepenthes in the rack, and half on a windowsill. The ones on the sill have been doing great, but some on the rack have been browning prematurely and wilting their leaves a bit. I *think* reducing the watering and repotting them in a more airy mixture has helped a little, but things still aren't great. I've let them get pretty dry between waterings recently, but not all the way. Some pictures are below, any advice is greatly appreciated!
N. spectabilis x talangensis
Next to the albo, you can see another plant where the basals are starting to not look so good.
