Help. What is wrong with my monstera adansonii

I can’t figure out what I’m doing wrong. The tips of all the leaves dry up. I don’t feel like it’s underwatered. I use a moisture meter. I admit the pot is too large, but it’s all I had when I received the rooted cutting. It’s growing, but those tips. I’ve tried neem oil, recently I’ve tried a copper fungicide. Any help would be greatly appreciated.
Any help is greatly appreciated.

That looks more like low humidity / inconsistent watering stress than a fungus to me, especially on a Monstera adansonii. The crispy brown tips and edges are really common with them indoors. The oversized pot may also be keeping parts of the soil wet for too long while the roots are still small.

I’d probably skip the neem oil and copper fungicide for now since I don’t see obvious signs of pests or fungal spots. A few things that may help:

brighter indirect light
let the top inch or two dry slightly before watering
higher humidity if possible
distilled/rain water if your tap water is hard
eventually move it into a slightly smaller pot with a chunky aroid mix

The good news is the new growth looks healthy, so I think the plant is still doing okay overall

Seeing the photo, I honestly don’t think this is fungal. It looks more like moisture/humidity stress from the oversized pot and possibly dry air, which is really common with adansonii. The plant still putting out new growth is actually a good sign. I’d probably stop the neem oil and copper fungicide unless you’re seeing actual pests or spreading spots, let the soil dry a bit more between waterings, and eventually move it to a smaller pot with a chunkier, airier mix once the roots develop more. Overall it looks stressed, not dying.

I agree with this take. The pattern on the leaves doesn’t really scream fungal infection to me either, especially since the plant is still pushing out healthy new growth. Monstera can react pretty dramatically to inconsistent moisture, oversized pots, and low humidity, and this guide on how to care for monstera adansonii https://botanapp.com/plant/monstera-adansonii explains those stress signs pretty well too. I’d also ease up on the neem and copper treatments for now because over-treating can sometimes add even more stress to the leaves. Letting the soil dry a little more between waterings and switching to a chunkier mix later sounds like the right move. Overall it still looks stressed rather than seriously sick.
