My Polly is getting yellowish brown spots on it. Dr Planta is saying it’s overwatering, but I don’t think that’s right. I’m not sure what it could be though, can anyone help? Also, the dry brown spots on the leaves were there before I got the plant, I haven’t seen any new spots since getting it. For reference, I’ve had this Alocasia for 2 months now. I repotted it in a chunky soil about a month and a half ago in a clear orchid pot. It has never given me new leaves, but it does look like more roots have grown. The roots are healthy white, no sign of rot at all which is why I’m thinking it’s not overwatering. I also check the soil with a wood skewer to make sure it’s mostly dry before watering. The room it’s in is on average between 65-70 degrees and 45-55% humidity. Within the last couple weeks I have lost 2 leaves but I wasn’t really concerned initially because they were the original small leaves. But now that these yellowish spots are showing up on the newer bigger leaves I am a bit concerned. I have checked this plant for bugs numerous times since I have got it and haven’t seen anything at all. I did treat it in the beginning with captain jacks bug brew a couple times. I know Alocasia are dramatic so I don’t know if this is normal or if I am missing something or doing something wrong.

    It is common for a Polly to drop a few leaves when any change happens-reporting, or just relocating are both normal reasons for it to drop leaves. The humidity is a little bit low. I know people can get them to thrive at 40% but if it came from a greenhouse I’d imagine the spots are a reaction to either a change in light or a change in humidity. You could also be watering too little. Polly prefer to be kept pretty moist all the time. I would increase light and humidity if you can, and then start watering when just the top inch is dry and below that you can still feel some moisture but not enough that you could squeeze it and water would come out. So long as you have good drainage it should all fine. One last thing it could be is over fertilization/fertilizer burn. If you want to try a fertilizer that will never burn your plants and prevent fungus gnats but also give you new leaves in no time I suggest Bios. It’s seriously magic.
