Hello mate, i used the biobizz products many times, every time that i followed the nutrients table, in the middle of flowering phase, i had a problem with the nutrient buil-up in the soil.
My advice is, try to use one times at week the nutrients and the other times use only water. Please take care about the ratio of Ca/Mg in your tap water because you are working with organic products.
Good luck and happy growing ;)
