Will post photo this evening!
I have had my Pilea for about 6-7 months and it just can't seem to stabilize.
Currently, I have several leaves with brown/black edges that are dry and then the whole leaf drops off. At the same time I'm getting leaves curling that weren't curling to begin with. It's mid-summer and I've had some new growth, but now I'm afraid whatever condition isn't right is going to catch up to the new growth and kill it off.
I've been very careful about not overwatering and I always wait until the soil is dry. It's in a room with an East facing window that gets bright light all day and direct sun part of the day. I had the plant in the window for a while but then I was worried about maybe too much sun and moved it about 4 feet from the window. It's in a ceramic pot with drainage in regular indoor plant potting soil.
On some of the leaves, before the spots turned brown/black I could kind of see them as transparent/yellowish areas on the to-be-afflicted leaf. I'm down to 3-4 healthy leaves now and the ones that are new are not growing nearly as fast as they were earlier in the spring, which makes me think I'm definitely doing something wrong.
Again, once I'm home tonight I'll post photos for additional info. Thank you!
Oh, and if it helps at all, I have a Monstera plant in the same room under the same conditions, it sits about a foot from the window and is the happiest plant I have.
