I got some BOG Lifesaver feminized seeds and they say they flower in 45-50 days.... question is do i have to wait that long to switch to 12/12 on my lighting? i dont want them to grow to tall so would it hurt to go to 12/12 like after 4 weeks even if there are no pre flowers yet? will this cause the plant alot of stress? would it cause less stress to top them and go the full 45-50 days or untill pre flowers form??
