I really don't know what's wrong with my Pilea.
It was doing fine, and then I think I over-watered it one time. A lot of its small, lower leaves went brown and mushy really quickly, and a few of the bigger ones near the bottom fell off. This was a couple of weeks ago. Since then, one by one the leaves have been getting black edges like this, and dying over the course of a couple days. I've been very careful with the watering, checking the soil well before watering, but can't seem to stop it. The plant seems ok otherwise - its little top shoot went black so I plucked it off, and since it's been making a new shoot which seems fine. It also has those little baby plants growing on the stem which seem fine.
Do I need to repot it? I was worried about the shock of re-potting whilst it was suffering. I do want to check the roots for any rot, but again I'm worried about stressing the plant out too much.
It's not in direct sunlight, or anywhere near a radiator.
Any advice would be most welcome. Thank you!
