In most of the US outdoors, plants are usually done eearly October at the earliest....some strains take into November. Either way, at least five or six weeks, as said above
Yeah they'll be pretty ripe the first week of October, 7 weeks is awesome but 4 or 5 more and you'll have some red hairs and cloudy trics for sure. Don't panic but I must agree the longer you wait, the better it's going to be.
