Considering first auto run; looking for input on setup

So after a run has completed with 7gal organic pots I was contemplating whether to try and pop a few of the auto seeds I've gotten from orders in the past before I do a tear-down/re-do of the space.

I've current got things setup as 6 x 7gal under 800w of LED (actual) and wasn't sure about plant size/spacing and what to expect. I figure I can go with 1 bean per pot and let it have some leg room but I keep reading about how autos just don't need big pots and would be fine in 2, 3 or so gal pots. So that leads me contemplating 1 bean per pot or 2... If it can accommodate the root mass/demands I can manage the plant size and scrog things, which was already the plan since I need some canopy management (plants just flop over and last time I yet again failed to get in front of the problem).

My feeding is manual/hand watering currently but plan to put a top-drip in place eventually - for watering primarily but occasional feeding perhaps as well. Hoping the soil has enough oomph left for a nearly water-only run after I top dress initially on replanting.

With coco plants only need 2-3 gal. For soil id still use 5 gal but 7 would be waste for and auto. I'd never put 2 seeds in the same pot. Roots want there own space.

Yeah I was hesitant on the 2 per pot due to roots fighting one another for space. And since i wouldn't be doing 2 of exact same strain per pot an even higher risk they'd have different growth characteristics... Probably just going with 1 per pot and 2 strains total 2x3... Pots are already in place and 7 gal so no reason to downsize since my intent is to top-dress and pop seeds in quasi-no-till style.
