I'd flush when the trichomes on the buds not the sugar leafs hit about 70% milky and 30% clear.. flush for two weeks or until you hit 20-30% amber for my perfected harvest time. 👊
Hey Growmie,
You start flushing 2 weeks before harvest to make sure all the excess nutrients are gone. Hopefully, I answered your question and remember ..."Happy Growing" and "Free your mind one puff at a time".
Hello
By the look of the video you have several more weeks before flushing. Start considering it when like 70% if the pistils are discolored and shriveled. Then you'll also want to get some close ups of the buds to try and see trichrome colors. But I'd say at least 3+ weeks to go.👍
