Thanks! I dont think a nute company would make that study so you can buy your nutes and because you followed what they said your weed tastes bad, that would make you not buy their nutes. Its great info since I only flush for fear of harsh smoke and because I reuse the soil and I dont want a soil full of nutrients because I plant from seed in the final pot and I make my supersoil anyway (light fertilized on top, heavier on the bottom). I will still flush because of that but I will shorten to 1 flush with epsom salts a few days before instead of doing 1 week or more like I used to, I always wanted it not to be true so I can feed them more but I never saw a conclussive study. Also it would have been cool if they used peat for the experiment too, not only coco and perlite, but I guess it wont be much different. It would also be nice if they gave more input on what their nutes have, I dont know if they are fully organic or not or what they are made of (anyone?). When I flush since I use fully organic my runoff water comes brown dark, which makes me think that it could also benefit since my soil is a bit saturated at the end of the grow, probably very high on ppm since I use peat coco with mostly peat. (I dont have an EC meter right now, or many of the tools I used to have, so I gotta go by experience)
