Burmeseanswered grow question 3 years ago Hi there, Autoflower normally start showing pre flower around 4~6th week into vegetative stage.Also I see in your diary ,you are growing with 24/0 light hour .Even though Autoflower are independent of light hour, growing without dark period causes them alot of stress.Try to reduce light hour to 18/6 or 16/8 and then wait for a week or two.They should be better.If they are not still showing any sign of pre flower after 6 or 7th week, again try to reduce 12/12 and you will see pre flower for sure.Sometimes that happen because of breeder mistake between auto and photo.Happy growing... ✌️
