Sorry everybody. my servers have been down since the 1st of June and I could not access email to review all the replies and goings on ion the forum. Everything is back up, and I am going through 5 pages of emails.
OK. Advice on FF. Grow Big is the only part of the system that has a hydro or soil formulation. Big Bloom and Tiger Bloom are not dedicated to one method or another.
I did not see where you have Tiger Bloom. You have to use Tiger Bloom with Big Blloom. Big Bloom is one part of the flowering formula. adding tiger Bloon is where you get all the ppm from.
You do not need CalMag with FF nutrients. Used correctly, you will never have a deficiency. The only way this would happen is if you allow your PH to be out of range.
