There's lots of good journals in the autopots section
https://www.autoflower.org/forums/autopots-watering-systems.329/ I pretty much followed Hansbricks setup. On mine I used coco bricks and rehydrated mine with 2ml/L Calmag the day before, when filling pots it's just the coco with no perlite or the clay pebbles on the bottom. Then the day I planted seed after germing I gave each pot 1.5L of light nutrient, voodoo juice, calmag again, made 1cm hole placed seed and covered.
