I just neemed mine. Pour a large cup or jar of water. It will all come to the top so you have to add liquid dishwashing soap. Mine says 1-1/2 tsp. per quart, plus 1/2 tsp. of dish soap. It will never mix without the soap! Pour in your nutes, hold your nose and pour! If you use a jar with a top you can save it if you have too much. Good luck.
