Thank you for taking the time to reply.
I have just attached new pictures. I am concerned about my begonia. Is my very first one and I love it.
I live in a flat in the UK, I don't get direct sun light but a lot of natural lights comes through the Windows.
I also got a humidifier to keep humidity over 60
When I bought my begonia it didn't have any leaf damage and now it started appearing...
I usually water from the bottom once a week or once I see that the soil is almost dried, I don't let it completely dried out as per instructions I have received.
I spray filtered water over the leaves once a week as well.
I only use filtered water.
Am I doing something wrong?
Looking forward to hearing from you!
Many thanks once again.
