hey there flowering starts after the preflowering , does that make sense ? for autos a breeder will usually give you the seed to harvest time... and of course that number will be off by like 2 weeks, be sometimes more. So to answer your unasked question, you have like 2, 3 or 4 weeks left ... and taking a secondary cola off now will be a waste as it just wont be potent at all... but it will keep your hands busy... and may actually trick the plant into thinking it's being attacked, maybe it will make more trichomes and terps in response... anyway sorry for the bad news, but it's the truth at least ! hope this helps ! 🚀
