Hey I got my mother the same type of roses that I have and we used the same potting mix but hers look like this and we both repotted them the same day. I added fertilizer to my mix though and I’m not sure if she might have. Mine is also in terracotta and hers is in a plastic pot, but both have drainage holes. She’s watered the plant twice since repotting it on Sunday because she thought it might’ve been a lack of water. Hers get a lot more sun than mine, so could it literally just be burnt leaves? I also technically bought it at a different location but same chain, so it may just be the care it received prior to being in our possession? I don’t know I guess I’m just looking to see if anyone knows what we should to to help this plant out 🤷🏻♀️
