Well it's in flower 9 weeks. Your 1st 2 weeks, thats still classed as veg.
9 weeks is a long time for an auto. Your buds/colas are huge. You giving them steds lol.
Anywaysvi wouldn't push it that long. 9 weeks in flower should be more than enuf. With autos, ripening is much shorter with autos 7-10 days. Lower your lights ppfd, as ripening needs 2/3rds of the light needed for fattening phase which is well and truly over.
