There are to many variables to even say man. Maybe 1-2 weeks like was said, or you might be right on. I can't say without seeing the actual plant. I'm sure they will be fine. As you get more grows you'll get familiar with when the plants are really mature and finished. I NEVER count days or worry about what the breeders say about a strain. I just grow them, give them what they need and harvest them when they are done. Its different for every single seed you plant, and sometimes its even different once you start using clones.
