@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) for your convenience: https://www.canna-uk.com/growguide :+1: hope it helps

@APOLLO, thanks again for the quick reply maybe was using to much calmag in my ro water (0.4) I'm going start raising ec to 0.2 from now on and use the half of the Recommended dosage take care thanks

I use tap water mate. Where we are water is soft and EC is around 0.12 - 0.14 some areas reaches to 0.2, if so, would require less amount of Calmag generally depending on strain.

@APOLLO,ok thanks for the reply I'm new grower was following your diary never realising a had Very hard water 0.6 sometimes 0.7 so my ec was high from the beginning so started using ro Water should I use calmag to raise ec to 0.4 or should I raise it more . Thanks mate again for replying Great diary learned a lot would be lost :laughing:
