Its completely upto you and what kind of stone you want from your bud the yellowing of the fans or sugars tells me she seeking nitrogen so your flush is working really well though you do still have quite alot of white pistils i assume this is fresh growth cause the pistils are curling back like they should you have a choice to make either you keep her going to mature the new growth abit or you chop her now and loose abit of yield the choice is completely yours personally i like to mature the new growth abit before i harvest cause i want the most weight but completely upto you bro nice looking plant anyway congratulations :) 👊
