So I have had an oz for like 5 months in a mason jar, I'm down to a half. Anyways it had its own distinct smell like any strain would except I opened it last night and it smell sweet. Kinda a gross sweet smell. Almost like puke but not that bad. The weed smell is very faint in the background but this sweet smell is stronger. Is it mold? I have checked for mold but im not experienced in identifying it. There are no cobwebs over the buds and there is no distinct white spots. Someone please help. Is there any way to identify mold from look, smell, or taste when you smoke it?
