Q.Arrowhead – Holes In Leaves, Brown Spots, Leaves Not Uncurling

Zone 48197 | Eniederm added on January 17, 2021 | Answered

I have had this plant for a couple of years and every now and then it gets leaves like the photos here, but it seems to have more lately. I recently moved down the street and it gets more light now (still indirect). It had a few fungus gnats a couple months ago but I was able to get rid of them. I think I fertilized it a few times over the summer and repotted it. It has one drainage hole in the bottom. I let the soil dry out slightly on the top between waterings. I almost never mist it, so I’m wondering if dry air might be a problem. There are no signs of pests so I’m not sure what’s causing this. The brown spots with yellow rings in the one photo make me think some kind of infection, but it’s only on one or two leaves. Overall the plant looks healthy to me and is still growing. Any help would be appreciated! Thank you so much in advance.

I think increasing the humidity will help, either by misting daily or adding a pebble tray beneath the container. The plant also may need repotting. Their roots grow quickly.
If the brown spots are just on a couple of leaves I would just remove those leaves.
