The conditions sound good 👍 so as long as there's no visible mold, I wouldn't worry too much. Weed develops the strangest smells during flowering but especially during drying. I once had an Amnesia Haze that smelled extremely like cat pee. It was almost unpleasant. However, it tasted very good, spicy and incense-like. I would keep a close eye on the buds, gently feel them from time to time but judge the smell only at the end of the process 😁👌
