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??

You can flower whenever you want, it depends on how tall you want them and how much light you have. No need to wait for pre-flowers just switch it over and it will do what comes natural. If you have something like a 250W light, then flower earlier for shorter plants. If you have something like a 1000W, then you can wait longer until they get up to 18-24" tall if you want.

For 400W, 8-12" would probably be best. You'll also want to LST, top, or pinch them to keep the growth kinda short. They will spurt into rapid growth for the first 2-3 weeks of flowering.

You can expect your plants to double in height in flowering. So wait till they are half as tall as you want them to be and then move to flowering.

Good luck.
