I have a Nepenthes rafflesiana and an unknown I bought at Home Dopt and I have them in a ten gallon tank with the heat at about 70 degrees and 80 most of the time. I also have it covered with a top that I put plastic over to create humidity. Which makes the plants pretty wet.
My question is. Why would the new leaves of my Nepenthes rafflesiana start turning black and the new pitchers as well. The other doesn't seem to grow at all. I've had them like this for about a month or so. Can someone help me with this problem?
