All 3 answers above are spot on dude. IMO - run light feeding and don’t stress the flush time too much - strictly speaking the plants roots will only take in the nutrients it needs and once you’re good to chop the only real advantage (again, IMO as this is a somewhat contentious issue) to the flush is sucking chloro outta the leaves, arguably making for a smoother smoke (also achieved with proper curing).👍😉. Good luck to the finish.👊
