Hey Josh.i have had some successful grows using autopots with Advance nutrients. pH is always between 5-6, ppm I start light around 500-800 ppm when plants first go in until established and then follow Advance nutrients schedule. My tap water is around 220 and when following the Advance nutrients schedule I am hitting 1500-1600. This seems high but my last grow did well. This grow my plants seem stunted at around week five. Only change was adding airdomes and adding an additional pot. I am removing my airstone from my resevoir tomorrow as you had mentioned it can change ph. Finally to the question, is there an optimal nutrient schedule for cannibis and the different stages of growth? I feel like I can’t just follow the Advance nutrients schedule because I always seem to run into some sort of nutrient issue. Also what nutrients do you recommend? Thanks
Kris
