I use Pro-Mix BX with mycorise for my soil-less medium. feed my plants with peters 20-20-20 & 1 scoop per 2& 1/2 gallons water & 1 ML Superthive during veg & switch to organic nutrients in flower. 50 ML Hesi bloom complex per 2 & 1/2 gallon water with 1 tablespoon molasses twice weekly & flushed with water only at the end of each week. superthrive is added once every 2 weeks for the first four weeks of flowering & then cut out of the mix. i then flush the last two weeks of flower with water only.
I think mine do rather well. never get nutrient issues or pf problems & they produce loads of resin
