That comes to 63 days as of today or 9 weeks. Allowing the first week to be for the change over to the start of flowering then it is 8 weeks of pistil/stigma & flower growth.
Some people like harvesting at this time for a more energetic effect. If that is what you want then think about the harvest taking place in the next couple of weeks. The trichomes would be mostly cloudy, maybe a few still clear and a few turned amber. Most of the stigma/pistils would be crinkled up and shrinking back down but still enough to be noticeable that are white or a light cream color.
Some would go another two or more weeks because they want a high that involves being locked into the couch. The recommendation is to look for about 10%, or slightly more, of the trichomes to develop an amber color. The rest would be cloudy. All the stigma/pistils would have turned a reddish to a brown color and be collapsed back down onto the bud.
Your choice. Harvest sometime this week for that energetic high or buzz. Or, wait about 2 to 3 more weeks if looking for the couch lock.
