Just some opinions.

hello,
I have a 400w digital ballast lighting fixture with MH for veg and HPS for flowering (photoperiods only) and I wanted to know if that's enough light for 5 sativa dominate femmed 420 carat babies in 2 gallon pots I know theres a lot of variables but general estimates would be a great help .. And also what do you guys think of the plants if you have any suggestions would help

It'll work.

But 5 plants in two gallon pots...i dunno...even if you veg a minimal amount of time the plants will grow out enough that they all wont get an ideal amount of light.

Sure it will work absolutely but none of the plants will generate their potential. All of the periphery plants will look just like that, like they have grown on the edge of light. if you trim all of the bottom branches and grow the tops of 5 if you trim all of the bottom branches and give the tops priority you'll be better off, actually would probably be better off with two lol. You can spin this 10 different ways but you only have 4 ft.² to work with. I've done it And those have been my results

Thats right. ^^ Any number of plants you want but youre limited to 4' sq of good light. Id go twonplants and scrog em.

It's actual measurements are 5.6" x 8.0" ( feet) and I think one plant isn't going to make it ... So it looks like it's going to be four if that changes anything

You won't have much room to work with, and they're going to run out of soil quick. Maybe look into some 5gal fabric planters and use the manifold training technique. That's pushing it though. It's hard to do 2-3 decent size plants under 400w.
