Since I don't have a ppm meter just yet but now ordered from Amazon....how many litres of water u have and how many ml of cal mag do u add per liter...just so I can get of enstimate
I use 1ml per liter of cal mag and there is 16liters in my dwc. I even add an extra ml just in case so a total of 17ml is this still too little.
Since I'm in flower should I be adding even more
