I got this fiddle leaf fig from a local plant shop about a month ago, and it's been pretty happy living on my southeast facing windowsill. I water it about once a week. I noticed recently that some of its leaves have brown spots in various places, and I am worried that it has an infection. I don't think it's a fungal infection, based on the lighter color of the brown spots, and the fact that I don't think I'm overwatering it (it's pot has drainage). I am worried that it has a bacterial infection, based on what I've read online, but I am not sure and I don't know how to treat it if it does have it! Can anyone help?
