Sour 60/berry Ryder tent grow

Ok so here it is, my first autoflower grow, so here's some info,I planted 3 sour 60(left) and 3 berry Ryder(right) I'm using a 48x48x80 tent, lighting is 1000 watt hps with air cooled hood, using 1/2 fox farm happy frog and 1/2 fox farm ocean Forrest in 3 gal smart pots, I have access to a natural artisan spring so I collect water from there, I have a ppm and pH meter and the water ppm is 14 and I adjust the ph from 5.5 to 6.2 before I water, running 500 cfm inlet fan and a 500 cfm exhaust fan and I'm also running a carbon filter, I'm gonna be doing some light stress training (lst) through out the whole grow. I saturated the soil 2 days before I planted the germinated seeds, I will just keep the top of the soil moist for the first week or so and after that I will start actually watering them, I don't have a set amount I water I just go by weight, I pick up the pot and can tell by how heavy or light it is if it needs water, I won't start nutes until I my plants show sex and i remove the males
