You have about 2 to 3 weeks left. I would get a jeweler's loupe and check the trichromes on the buds not the leaves. When you have a 10 to 30 percent amber mix with cloudy ones is your optimal window. Unless you want more couch lock effect then wait longer. Dates on packages are not correct and mainly a marketing gimmick to promote sales. Only way to come close or hit their time frame is to have perfect conditions the whole grow.
