That’s one of the reasons why I want to know how long my plants have been flowering. I might be wrong… but a I would think it’s not so much about perfect grow condition and more about genetics when it comes to a plant maturing.Keep in mind that breeders come up with times they advertise under their perfect grow conditions and feed schedule. Most of us can't duplicate that so most will go longer than advertised with a few exceptions. That's been my experience anyway, YMMV.
