Can you use cal-mag plus with vitalink a+b bloom in hydroponics? as vitalink has 3%calcium init and i think my mate has a calcium deficiency he is in the first week of flowering! There is a picture attached he has used epsom salt but it doesn't seem to make much difference so it cant be a magnesium deficiency.
