This thread could stir the hornets nest I realise, but I've seen it for myself. Tried pumping it full of chems, took weeks to cure off the green taste. Last run used only bloom and a little veg the first few weeks, I'm talking 600ppm max the whole grow. Obviously some plants are more hungry but the point is I was bare minimum and to be quite honest it was the nicest tasting stuff I've had in a long time. I intend to do the same on the run I just started, but using HPS instead of LED for flowering this time so it will be interesting to see the harvest weight.
