m0useanswered grow question 2 months ago Depending on your geographical area. summer hours are close to 12/12 at the equator. but where I'm from its closer to 18/6 So you want to measure out how long they are getting darkness for. some strains need aorund 10hrs darkness others a bit more. also if it is heavily shaded from other buildings and stuff it might increase that darkness period before light hits em.
Will it bounce back into veg mode, maybe if the light is greater then 12-14hrs a day. you will notice this new regrowth is odd and lots of single finger leaves growing out of the bud sites. But I don't think this is going to happen.
It does indeed look to be in flower, I doubt this is it just showing sex, its a bit aggressive. Maybe the shop that sold it to you misspoke when they said it was an autoflower, and that it was an autoflower mix? I have heard of fast versions "photoperiod + auto" not being great mother plants and turning auto in the next vs photo. There is not a lot we don't know about them as they are someone what new on the market.
Maybe after a long veg time the auto part takes over? If the other photoperiods plants are ok its a working theory but not proven.
I agree with other answers in previous questions to have an auto veg out for 15weeks is unheard of. not to say its impossible but it would not be something someone would want and it had a lot of stresses like topping so it seems highly unlikely.
Just keep giving it lots of love and maybe more food given its entering flower and will be eating it up. Your plants are looking good so well done.
