I don't know Bio Bizz very well but I used them at the beginning and I remember that they kept Bio Grow until the end in the card and in flowering they insert Bio Bloom, the others move on to the flowering fertilizer and add enzymes. I recommend that you check the pH well, if you don't do it or you do it with that basic yellow tool that is on Amazon find a good Ph pen. Because sometimes you are giving the nutrients but with a pH that is too high they cannot be absorbed. I give Cal Mag when there is a magnesium deficiency and a little bit as you said above all in the first phase of flowering if there are no problems with deficiencies. An excellent article on the use of Cal Mag was written by RQS find the one in your language https://www.royalqueenseeds.it/blog-cal-mag-per-la-cannabis-tutto-cio-che-c-e-da-sapere-n1530
