My mint is struggling and I don’t know why! I tried the Dr Planta diagnose twice and it says overwatered, but I followed all the steps and it’s only getting worse. The soil is still damp and it gets lots of light. A few hours of direct and a few hours of indirect sunlight in total about 9 hours a day. If light is the issue, I could move it to have direct or indirect sunlight all day if needed. But I’m not sure which one to try. Should I fertilize?
