<span class="link_user">@jmendesp</span>, According to Canna&#039;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) for your convenience: https://www.canna-uk.com/growguide :+1: hope it helps
