I recently got this Peperomia Obtusifolia as a gift last week, and am wondering what these brown tips are. They are only on the underside of the leaves, and only some leaves have them. I am keeping this plant on a 2-3 week watering schedule, as it is in the winter, but when I received it, some leaves did have brown spots, but I pruned them off.
I did some research and still don't know what has caused these brownish tips and if they are harmful or not. I am keeping it in bright indirect light and have not fertilized it.
Also, there is some odd yellow speckling which I have kind of not worried about, but it's only on a couple of leaves (like 3 or 4).
