Hi All, Hope someone can help me with identifying... what's wrong with my mint leaves. There is a form of... discoloration on the leaves... it's been like that for pretty much it's whole life (since 3 months ago, that is). Could anyone tell me what it is, and what to do to help it? Is it mint rust, some fungal infection, etc?? Thanks in advance for your help. Pictures attached. Would worry too much about the black dots, prolly stray soil that blew onto it.
