How to get the most out of these ladies?

Hey guys my plants are 3.5 weeks old. They are Banghi Haze, FFOF, 6.5 PH water, 3 of them are topped one is not.
My question is what method should I go to get the most potential out of these babies? such as trim up under, top again, fim, lolli etc.
Thanks for the input.

Depends on how long you're planning on vegging, but top them 2-3 more times to get many bud sites, pinching main branch for knot-- aka super charged nutrient/water uptake, and then lolli once it hits desired height. Don't forget some stakes or a net for heavy tops. Good luck!

Do a combination of topping and LST. Top the plant, then when the tops get healthy and a bit bigger, top the tops again. LST all side branches.

thanks for the input fellas!
