You don't need all that. Micro, grow, bloom, and some cali-magic.
Follow the GH chart. If it says, 5ml micro, 5ml grow, 2.5ml bloom with a ppm range of 600 to 900ppm.
600ppm is the smallest dose. 750-800 is a half dose. 900 is a full dose.
Respect, but you're going to jack things up making a soup with all the extra stuff. Using the Epsom salt is adding ppm you do not need.
so no A and B or yes A and B?
