Floranova bloom and cal/mag

Hey everyone, I'm in week three of flower using hydroton as my medium, R/O water, and floranova bloom with a couple additives. It seems as though my plants are having a bit of a calmag deficiency, but i thought floranova was supposed to have enough calmag in it? Anyone else experience calmag deficiencies while using floranova bloom?

i am currently experiencing it now in soil using the same nutrient. adding 10 ml cal-mag/gallon every other feeding til harvest.

R/O also will cause a calmag deficiency also, which I learned the hard way.

Thanks for the response. Hydro store guy told me that floranova bloom has all the cal and mag in it I'll need. He was wrong.
