What's this brown spot on the leaf of my jade plant? I first saw it on the leaf about a week ago. A few days before I saw it, I had to remove one of its bottom leaves because it looked like it was rotting. I'm an amateur plant parent, but I'm thinking it could be overwatering, root rot, pests... What do you think it is?
I'm super attached to this jade baby because it's the first plant I ever propagated, so I hope that whatever it is, it's fixable!
