thanks dt
that stretch sounds like the stretch of the tahoe og, which i think tahoe is best if you take her down between 66-70 days of 12/12. mine stretched less because i topped them both once and trained the branches to bush out, since she is stretchy and apically dominant this really plays out well and turned some lower branches into top colas. for the first two weeks of stretch i would bend the tops down and out away from each other.
so dont take those longer than ten weeks, none of the ogs go longer than 10 weeks to the best of my knowledge.
another tip i can give you is, chop it when the smell reaches its peak, youll know you went too long in flower when it loses its smell, so if you are at day 65 and it smells dank as hell, dont hesitate to bring her down. sometimes the tops finish sooner, if you want you could leave the undeveloped buds on the branch to finish maturing, i just use them for hash.
here's a pic i took of tahoe og at 5 weeks, dolled it up its my new avatar
