20 plant auto ak47 grow

hi im starting my nxt grow 20 auto ak47's in 11l pots in a 1.2x1.2x2.0m tent using a 600w hps, the pots fit into the meter square tray comfortably but will i have a problem with over crowding? obviously with 20 regular ak47 i would do but with autos staying relatively small what do ya think people ?

I'm planning on growing under a 600whps in a 1.2x1.2x2m tent for my first grow, what yields are you expecting form this grow?

the review of the strain said around 30g per plant
