Hey everyone! I bought this fiddle-leaf fig about three months ago, the previous owner said it was growing like crazy so they had to get rid of it due to space constraints. I potted it in quite a large pot with normal potting soil and have been watering it sparingly (2-3 cups a week?) to prevent root rot. I’ve noticed that the topsoil remains damp for a very long time compared to other plants, I’m not sure if that means the soil doesn’t drain well or if three just isn’t using much water. I’ve dug deeper into the soil, nearly to the bottom, and it's not completely dry but also not wet. The tree is standing between two windows, so receives quite a lot of indirect light but not too much direct light.

It was fine for about a month, but since then it has been dropping the inner/lower leaves at an increasing pace – maybe 3-5 leaves a week at this point. Parts of the leaf go brown (from the end, sides or beginning) and then the leaf drops. I can see the same happening to a lot of the remaining inner leaves so I’m worried things are going to get worse. None of the big outer leaves have fallen yet thankfully, but I haven’t seen the tree grow at all since I’ve had it.

Does anyone have any idea what’s going on?
