I finally caved and bought the much desired monstera deliciosa about a week ago. I had to resort to ordering it online (which I’m always nervous about) because it’s so hard to come by where I live. I was actually very pleased with the condition it was in when I received it. The roots looked great and all the leaves looked healthy - except one. I noticed it had a slightly yellow edge and some small dark spotting. Any clue what this could be?

I potted it up and gave a good watering and a week later, it looks like the yellowing/spotting grew a bit. No bugs or anything like that that I can tell.

Pictures attached! One is the problem leaf and the other is just showing a healthy leaf.

Thanks so much in advance!!
