What is the medium? Soil, Coco, hydro, aquaponics etc.

soil

Soil or soilless? There's a big difference if soilles mixyou wNt to be at 6.5 , it's the sweet spot for nute uptake for this medium. You won't need cal mag until about week 4 of flower as a rule.depends on your water ph level, I rarely use down, use down if above 6.5 to bring it to this point and vice versa with ph up
