I have had my monstera for a few months and have recently received a Rubber plant as a gift. I noticed that one of the leaves on the rubber plant had a small 'torn' hole but didn't think much of it.
This torn hole is now on another leaf on my rubber plant, and it seems that my Monstera who sits next to it has also develop brown rimmed markings and tears, similar to my rubber plant.
It looks like a bacterial issue but I'm not 109% sure. I have attached images.
If you know what it could be, please let me know and how it might be remedied.
