i have a buddy who chopped his down on day 62 so thats just a day shy of 9 weeks, one thing i noticed about few kush's is they show off some signs of early maturation then chill for a while then show more signs of being ripe, i have a master kush that did just what you are talking about but i knew it couldnt be ready that soon, i think 60-65 days for most indica dom kush should work
