Hello I bought my bonsai tree about a month ago and now since maybe two weeks ago I've started to notice that some leaves is starting to turn yellow/become pale and after a while falls off the tree. The leaves doesn't sloke or curl and the tree looks rather healthy otherwise some of the leaves that falls off are also slightly brown in the edges. Not all of them though.
So I've some things that I might think it can be:
1. My tree doesn't get enough sunlight. I live in the north were the sun is only up some hours a day.
2. It has recently been quite cold outside and maybe (even though my tree lived inside) this change in weather makes my tree stressed.
3. I water too much/too little. The soil that came with the tree is very well drained and when I water the water starts to sip out of the pot pretty quickly so maybe it doesn't have time to take up everything it wants.
4. My tree doesn't get all the nutrition it needs.
5. The humidity is too low (hence the brown edges I'm thinking).
If you have any experience with the problems me and my tree is facing please tell me what you did or what you believe can be the reason.
