First time grow

Hi all.
This is my first try to grow autos on budget. Ordered 15 seeds from seedstockers.com 5x Big Bud auto, 5x Amnesia haze auto and 5x AK420 auto. Seeds arrived in a week, germinated by soaking in RO water for 24h and used paper towel after. 100% germination, but one girl been damaged by accident. Planted germinated seed into 5x5gal fabric pots and 4x3 gal pots + 5x1L pots.

Tent is 4x4x6.5 (120x120x200)
Light 600w dual spectrum HPS
Budget no brand 5" carbon filter with fan

For this grow I've decided to grow in soil with perlite, I have used Westmidland multipurpose compost with added John Innes. Nutes BioBizz grow, bloom and top max + calmag and mycorrhizal fungi.

I will LST 5 and 3 gal pots later, and ill try topping and FIM-ing 1L pots

Any advice welcome
