I would chop her if all trychoms are cloudy. Amber trychoms causing couch-lock is bro science. But taste and smell can def change. Thca converts to thc and then to cbn when in contact with oxygen. This happens also after chopping her down , when she's drying, untill you place your buds in an airtight container. In my experience waiting too long for harvest, can fuck up your buds smell and taste, cause bud rot and even the structure of your buds can suffer. Some strains/phenos even don't get amber trychoms or it takes them extremly long. So If all are cloudy and you like her smell don't wait too long.
