Hello, I’m a fairly new plant mom & have been troubleshooting this plant for the last month. At first I thought it was infected so I started spraying it with copper fungicide. That seemed to help a little bit I could tell the problem is deeper. I was finally able to dump the pot of soil to check the roots and this is what they look like. The flower shop that sold me this plant gave it to me in a planter that had zero drainage holes, so the soil was super moist even tho we’ve only watered it minimally. 😫 Do yiu think the brown spots and sickness was solely due to no drainage or something else too? I’m repotting today with my own mix of good draining soil, perlite, peat moss. I pray I can revive this beauty. Should I just trim the brown part from the leaves or what else can I do to help this sick plant? Any advice would be greatly appreciated 🙏
