@jmendesp, According to Canna's recommendations, I would put calmag in water until its EC is reached 0.2 (for me, i add 1 mil calmag per 4 liters of water, makes the EC to 0.2) . so your answer is 0.2
I THEN add any nutrients (half the dose as advertised by them just because some strains are moody so always better to increase them gradually)
