I'm hoping someone can help me figure out what's going on with my N. spectabilis x aristolochioides. The most recent leaf is distorted, as is the tendril (it's curled backwards). I thought it was a fluke, but now the newest leaf that is unfolding is showing the same problem. I've also recently noticed some small webs around the plant. My first thought was spider mites, but 1) I can't seem to find any on the plant, and 2) it's my understanding that they won't survive in humid conditions, and this plant has been in the direct line of my humidifier for the past month or two. I'm seeing some webs on a couple of my other neps that are right next to this one, but have not seen any of the leaf distortion in them. General conditions: growing under lights, days 75-80F, nights 58-65F, humidity between 40-60% (though probably a bit higher since it's so close to the humidifier).
Any thoughts on what this could be and how I could treat it?
Thanks in advance.
