All things brown leaf spot, leaf drop septoria fungus here..
Wet fall in parts of North America and septoria is exploding!
Let's talk about it here, as it can be very hard to diagnose and it looks differently at different stages, imitating many different common plant issues!
You'll also notice there's not much info about it indoors on the internet for some reason, but let's try to change that here..
This brown spot with the ring around it is often the first, and most specific indicator of septoria (and very easy to miss)
.. the rest of these pictures are also septoria, tho often initially misdiagnosed as calcium, mites and/or other more common issues
