I don’t count days but if I have to guess I would start counting the days from the first sings of preflower white hairs. My last grow was ak47 auto from this site and it says 56 or 58 days it veg for 16 days before the white sexing hairs showed up then 58 days later the plant was ready to harvest with my ideal amber milky tricome ratio taking a total of 73 days …I don’t go by the days because that’s justba rought estimate because at the end of the day is the plant who decides how long she needs. But my opinion, start the count when she starts preflowering when you see the tiny white hairs (pistils)
