How much of the various Greg Watson ferts do i mix into 250ml of water? I was dry dosing, want to try this way. I know about the calculator on Chucks site, but not sure still. I see to calculate it to a certain amount, say I make enough for 1ppm, and the targe he says is 5ppm. Does this mean i should put in 5 ml 3 times a week, since i'm doing EI? Or should the total be 5ppm for the week? Any help is appreciated.
