Leaf spots and discolouration

She’s definitely outgrown her current home. I would definitely transplant into a bigger pot and I would consider using fabric pots as overwatering becomes a non issue, the roots will auto prune themselves once they hit the edge and it doesn’t get root bound around the edges anymore. Just make sure you don’t let the fabric pot sit directly on a tray or whatever surface. Keep air flow under there. A transplant and a good feed and she’ll bounce back for sure. Leaves curling is a symptom of being or showing signs of being root bound. Good luck friend 🤙
