My mint may have an issue, help is appreciated
Hello, this is my first time posting here.
I'm going to get straight to the point: my sweet mint plant seems to be having issues. I'm growing it indoors, but sometimes set it outside in the sun for a few hours (I live in the hot area of Florida, saying this for reference). I've not had any problems growing mint indoors yet; however I'm slightly concerned for this plant. It seems to have a strange discoloration on its leaves, where it's brown with tiny dark brown/black spots. I'm not sure if this "mint rust" or some kind of infestation, and if I should toss the plant or try my luck with it. I bought it from a garden center; it is not home grown.
I really do enjoy mint plants, so I'm hoping this one is still savable!
