This is what the plant overall looks like:
I assumed the plant was doing fine, but today I found its first fallen leaf. After that, I started looking more closely, and found several leaves hanging, half broken. One of the leaves weren't broken, but looked kind of dry/sick, and the moment I touched it, it just snapped off.
Here's a group of photos from the plant that might help:
The plant is about 3 meters from two south facing windows. I water it a moderate amount about once a week, when the soil is slightly dry. I live in northern Europe, so right now we have maybe 7'ish hours of daylight.
Also there's this, which have been like that since I bought the plant 6 months ago, so I'm not sure if that has had any effect.
Anyway, thanks for taking the time reading, and possibly helping!
