I never have runoff and never flush. My weed tastes and smokes fine. But, I feed just the bare minimum without a bunch of additives at a very low EC compared to many.
Old post, I know... But ran across it doing some forum searching. I've seen your plants and they always look wonderful. I'm still fairly new to coco, but I personally am a heavy feeder (1.8-2.5ish) ec, but I drain to waste and get plenty of runoff.
Honestly, I'm beginning to really think about how much nutrients I am wasting and I dont like it. I've considered feeding with your style (low ec, little to no runoff). So what EC/PH do you consistently feed at?? Do you ever have calmag deficiencies feeding at a lower ec? Or do you make up for it by adding extra? I tend to get calmag issues specifically magnesium when I don't feed at least full strength. My tap water comes out at 160-190 ec, so its on the lower side.
Any other tips you can give me? Appreciate it brother.
