I've got this Ficus Benjamina for about 3 months now, I think the tree is maybe 5,6 years old. At the begining (in the winter) it was doing ok, but now I have noticed that the leaves are turning yellow and falling off randomly, not from the bottom, and very fast. The tree is losing 5-10 leaves a day and I have no control over it. The yellow leaves that you see at the photos turned yellow today and will be on the ground tomorrow. I also noticed that the other, healthy leaves are a bit curly, I don't know if they were always like that or if its a new thing. Some basic info:
1. the plant is in my kitchen, which is bright after 12 pm. No direct sunlight, but also not at the window
2. I water it everytime I notice that the soil is dry (3-5cm, not the top), which was about once in a week
3. The room temperature is around 25C
Also, the weird thing is that these pictures were made today, and I've watered the plant yesterday - it looks like the soil is dry again. I water it everytime until the water starts getting out of the pot holes, then I remove the water from the plate, so the plant never sits at the water.
Maybe this is a normal thing for this plant, but if it's not, any advice will be helpful, thank you
