I've been treating my N. Maxima for some sort of mite like pest with 1:4 solution of isopropyl rubbing alcohol for the last 6 weeks with slow but steady success, however now a number of the leaves are showing an orange/brown tinge. I would normally think they are just sun-tanned however the leaves don't look dry enough and there has been little sun recently. Could it be something to do with the alcohol treatment or pests? Here's a video as my camera isn't working, sorry about the crappy quality. Thanks for any advice!
