Plants can stretch to 2-3 times their size in the first three weeks of flower.

Height and width are typically the determining factors of when to switch.

You can veg them as long as you want. If you have the space, I'd go a little longer for a better yield. Just remember, if they are 3ft tall when you switch to 12/12, they will probably end somewhere around 4ft.

I just go straight from 24/7 to 12/12. Look up negative temperature differential to help limit the stretch if you want.

Are you running an auto OP? It’s kind of important info when deciding how to set up your light schedule.
