Actually; I use all these Primary, 2ndary, and Micronutrients. In fact; I add Boron, Molybdate, and copper, also.
I do notn useAluminum sulfate, but I do recommend dolomitic crushed lime. However; As recommended in that article; It needs to amend the soil for a coupleonths before you plant in it. So; Yopu can plan ahead and make soil ahead of time, but I have never needed to go through all this. I just use a product called Rainbow mix, and I use my solution, or Dutchmaster Advance, A+B, Zone, znd Silica.
my solution contains Calcinit, Potassium Nitrate, Magnesium sulfate, Sulfate of Poatash, MAP, MKP, This covers all the Primary and 2ndary Nutrients. I have 2 concentrates from this A and B. I add my iron “Fe 13%” into my part A
My Micro is made up of; Zinc, Manganese, Magnesium, Ciopper, Molybdenum, Boron.
I PH my solution with Pure diluted Sulfuric Acid.
Don;t know if this helps, but since it was mentioned; I thought I would give you my take.
I feel that if you adjust your Solution PH to balance out against the soil PH, you will leave residual salts in the soil that should eventually keep your PH balanced. At least it works for me.
Keep in mind; I grow some veggies, and an occasional MMJ in soil or PtoMix BX. With that said; I am a commercial hydroponic , Fertigation farmer. I take seminars at Clemson University in conjunction with USDA certified training. I have done surveys for Rutgers, Purdue, and NC A & T.
My mentor is from S. Africa. He taught me how to make this and other solutions. He now works for Canna Nutrients. 
He’s pretty good
