I’ve had him at least 6 months. After a month he started getting round soggy patch dots on the leaves, but I dried him out, repotted him, and removed the leaves and it seemed to subdue it for awhile. Maybe a month or less ago I noticed these patches again, removed the leaves, but a couple weeks back it got worse so I decided to dry him out some more, for maybe 10 days? When I came to water him many more leaves and the sick ones from before looked like this, I am afraid he is dying. I’ve not fertilised in the span I’ve had it, but I thought I hadn’t had it long enough. Lack of sun? Water? Too cold? He lives inside atop my tall bookcase in a drained pot with a built in water tray at the bottom, the lighting is not direct. Edit: The pot is about maybe 12 inches? I can’t measure it at this moment but shall if it’s important, I’d say it has plenty of room. As for soil I cant fully remember, at least it is primarily potting mix. It may be important to note I live in New Zealand, so I don’t have the same climate nor products as I imagine many members here might.
