hey kalikushmush, i think see why you want to count the flowering weeks, probably so you can time the chop right? yeah dont do that, first the breeder almost always will give you a shorter flowering time than you will have, usually by two weeks, but sometimes more even. Second you should time the chop based on the trichome maturity not a (arbitrary?) number of weeks. get a 60x magnification, and check until you have 100% milky trichomes. Third it can take some plants over a week sometimes even two weeks to start flowering from the flip. So base yourself on when you actually see the flowers rather than when you flip. Hope this helps ! 🚀
