Today I noticed the new leaf on my N. burkei, which hasnt even unfurled yet, is a sickly brown shade... The plant has seemed otherwise healthy and none of my other plants are exhibiting this. I dont believe it could be pests because I grow indoors and havent introduced any new plants in years, but I guess its possible I tracked some in on me...? Not sure.
The plant hasnt been repotted in 3+ years, is it possible it simply needs some new soil?
Thank you for any responses! Id like to get this figured out sooner rather than later.
