Getting worried about a couple of my plants. Lower leaves looking like this. Can't find a match on the diagnostic charts. Any advice much appreciated. Thank you
I had to move them into the shed bc of wife's allergies. Decided to take a look at the soil of the worst one. All the perlite had accumulated near the bottom and the soil was wet and smelly. So I think this was the main issue. Replanted into dry perlite and soil. Hopefully will be ok.
