Lucas Formula, cal/mag and silica

[Gammagoat]

Trying to simplify things a bit I decided to use Lucas formula for next grow. I'm using RO in perlite ammended sunshine#4.

I see from the bottles of Gh floramicro that it has cal at 5.0% and that florabloom has mag at 1.5%. Will this be enough cal/mag with out the addition of a separate cal/mag sup?

Depends on strain and medium but I only needed extra cal mag around weeks 4-5 in bloom running Lucas in peat/perlite. Using AN Jungle Juice.
