Doesn't matter what it says.
Nutes alter the ph of the liquid.
If you ph adjust then add nutes then your liquid absolutely 100% will not be the appropriate ph.
Would you add salt and pepper to adjust the flavour of your soup before putting the chicken stock in it?
Same thing.

From the guy that ph adjusts then adds nutes thinking it doesn't change it.
Call me whatever you want if it makes you feel better mate.

I think it might be you.
Yes, calcium in calmag will react with pH down. So will your base nutrients, much more aggressively. That’s why you can only appropriately adjust pH of the solution once all reagents are added. Calcium additives first, then base nutes, then adjust pH.
If you are adjusting pH before you add base nutrients you are missing a step, or adding an additional one for no reason.

has nothing to do w/ my feelingsFrom the guy that ph adjusts then adds nutes thinking it doesn't change it.

you are simply ignorant of the infos presentef here

you actually got something constructing to add chump?

Yes, lots “constructing”, a big step you missed: don’t pH before you add your base nutrients.
Even the literature you posted agrees. I wonder if you aren’t understanding what it says? I notice English seems to be a second language. No disrespect intended, just an observation.

Haha superb, his own "proof" says that he's wrong. Wish I'd read it now. Gutted I missed the opportunity lol.

LOL u realize that Calcium & Magnesium is nutrient just like any other plant food?
Base Nutritent != Micros
"Use the next steps:
1. Calculate the fertiliser recipe in the following order: H + , Cl, Ca, NH 4 , P, Mg, S, and K in mmol/l and
choose the most appropriate fertiliser ingredient so that all the ions are presented in the list of fertiliser
ingredients:
a. Choose nitric acid or phosphoric acid to add H + to the recipe.
b. Choose calcium chloride or potassium chloride to add Cl.
c. Use calcium nitrate for Ca.
d. Next to the NH 4 contribution of solid calcium nitrate, use ammonium nitrate or MAP to complete the
NH 4 demand.
e. Choose monopotassium phosphate to complete P.
f. Use magnesium sulphate to complete the Mg or S demand.
g. Add magnesium nitrate if more Mg is needed, or replace magnesium sulphate with magnesium nitrate
if less sulphate is required.
h. Choose potassium sulphate as a sulphate source in case the sulphate demand is not completed with
magnesium sulphate.
i. Use potassium nitrate to complete the NO 3 and K demand.
j. Select the appropriate fertiliser ingredient to supply each micronutrient."
9. PREPARING HIGHLY CONCENTRATED
STOCK SOLUTIONS
[snip]
Micronutrients are put into tank B in case they are added as sulphate salts. Chelates can be put in both
tanks. If substantial quantities of acids are used, however, it would be preferable to place the chelated
micronutrients in the A tank. Chelates are sensitive to low pH levels in the tanks: at a pH of 3.5 or
lower, the chelate structure will break down. This is especially true for the EDDHA and HBED chelates.
Therefore, to avoid low pH issues in the A tank, the quantities of acids in the A tank must be limited to
only a few litres per m³, while the remainder should be put in the B tank.
The pH of the stock solutions in both tanks should be lower than 5 so that all the fertilisers will
completely dissolve.
Filling the A+B tanks
Thing is, if you make a solution that contains micros and poor pH-acid drops into it then you locally have a region that will be quite acidic and do some damage there - until the acid is dissolved. Just to prevent that you want the acid to work on Calcium-compounds.
Good you fellas started to read at least

Your massively over complicating something that's extremely simple and you don't actually understand what it is your talking about.
Nutes get ph adjusted once they've been mixed. Not beforehand. End of.
There are no ifs or buts that's just the only way it can possibly work.
Educate yourself before trying to school others buddy. This why so many new guys fuck up their first grow.
People spouting random nonsense at them while trying to make themselves sound intelligent.
