I have the utmost respect for you!
Takes humility to reassess ones methods. I have stayed away from a.n nutes due to their complexity.
Try looking at cutting edge solutions. Seriously 3 things. Can add others if you wish. They have a online calculator I use every time. I rarely add anything but cal and mag.they are in seperate forms. They have a sloar Gaia line for soil/ may be organic too. I just use tap. Took the nute side out of the equation so I could learn from the plant.
I'm not a super star grower, yet. So you come on back when your settled.
