One of my plants (4weeks in flowering) starting to smell very sour, close to sour milk but not that nasty of a smell, sour is a good way to describe it. No mold, strain is G13 Blueberry Gum, anyone grew this strain before, what smells did you get. The smell if definitely coming from the buds, getting nice trichome coverage. Is sour smell bad or normal for this strain? Thanks!
