All in One -Fertilizer making- Recommendation!

[Hanuman]

Hello everyone...

I want your help and advice.

I don't know if I'm doing it right in all-in-one fertilizer production.

I will be glad if you tell me the mistakes I made.

First, I add them to the solution in order.

1-Fe 7% DTPA--I use 5 ml of hydrochloric acid in 100 ml of distilled water and lower the pH to 0.6-- Then I add 0.32 grams of 7% iron dtpa. Then I add 100 ml of this to the main solution.
2-Fe Gluconate 11% (E579)--I use 5 ml of hydrochloric acid in 100 ml of distilled water and lower the pH to 0.6-- Then I add 0.27 grams of 11% iron glukonat. Then I add 100 ml of this to the main solution.
3-Fe EDTA 6% (E579)--I use 5 ml of hydrochloric acid in 100 ml of distilled water and lower the pH to 0.6-- Then I add 0.24 grams of 6% iron EDTA. Then I add 100 ml of this to the main solution.
4-MnSO₄·H₂O --5 grams edta--3 grams of ascorbic acid--5 ml of hydrochloric acid is used in 500 ml of distilled water and reduces the pH to 0.8. Then I add 0.31 grams of manganese sulfate. Then I add 100 ml of this to the main solution.
5-(ZnSO₄.7H₂O) --5 grams of edta--3 grams of ascorbic acid--5 ml of hydrochloric acid is used in 500 ml of distilled water and it reduces the pH to 0.8. Then I add 0.45 grams of zinc sulfate. Then I add 5 ml of this to the main solution.
6-Boric Acid (H₃BO₃)-5 grams of edta--3 grams of ascorbic acid--5 ml of hydrochloric acid is used in 500 ml of distilled water and lowers the pH to 0.8. Then I add 1.18 grams of borik asit. Then I add 5 ml of this to the main solution.
7-Copper Sulfate Pentahydrate (CuSO₄.5H₂O)-5 grams of edta--3 grams of ascorbic acid--5 ml of hydrochloric acid is used in 500 ml of distilled water and lowers the pH to 0.8. Then I add 1.21 grams of copper sulfate. Then I add 5 ml of this to the main solution.
8-Sodium Molybdate Dihydrate (Na₂MoO₄.2H₂O)-5 grams of edta--3 grams of ascorbic acid--5 ml of hydrochloric acid is used in 500 ml of distilled water and reduces the pH to 0.8. Then I add 0.259 grams of sodium molybdete. Then I add 5 ml of this to the main solution.

After adding the micro element additives, my pH remains 0.7.
Then I added 15 ml of hydrochloric acid and lowered the pH to 0.2.

Next steps...
1-I add 6 grams of ammonium nitrate to my solution.
2-After the ammonium nitrate melts, I add 19 grams of potassium sulfate.
3-After the potassium sulfate melts, I add 9 grams of magnesium sulfate.
4- After the magnesium sulfate melts, I add 1.3 grams of Monopotassium Phosphate.

Is my way of doing it right, do you think I'm lowering the phs too much?
After all the elements have melted, the solution pH is in the range of 0.35-0.40.


These are the available salts I have:

1-manganese sulfate
2-zinc sulfate
3-boric acid
4-copper sulfate
5-sodium molybdete
6-EDTA
7-Ascorbic acid
8-salicylic acid
9-potassium sulfate
10-potassium nitrate
11-potassium chloride
12-potassium oxide
13-ammonium nitrate
14-ammonium sulfate
15-urea
16-mono potassium phosphate
17-fe edta 6% ---fe eddha 6% ---fe dtpa 7%--fe gluconate 11%
18-potassium sorbate
19-magnesium chloride
20-magnesium nitrate

Ok so I have read the thread and at no point did I see anyone cautioning you about using strong acids and in such quantities (maybe I missed a post?) I am bewildered!! 😳 So I will do this like I was once warned by @dw1305. What you are doing is dangerous and there is no need to use these acids to make ferts unless you are producing them at a commercial/industrial level. You can use much safer alternatives like ascorbic acid, vinegar or other mild acids. Plus you keep adding and adding acid again and again, not sure why. Or maybe I didn't understand something. The process seems convoluted. The point being that the more you add the more you increase the chances of some accident happening. Unless you are a chemist, which I don't think you are, else you wouldn't be posting here, I suggest you ditch the hydrochloric acid galore and use safer products.

There is also one thing I didn't see mention and that it is highly advisable that you use a chelated Fe that is 11% or above. Reason being that the lower the Fe%, the more chelating agent you have thus increasing your PH and potentially initiating a chemical reaction with phosphate and/or other elements. I wouldn't recommend anything below 10%. Now considering that you have brought the PH down to an astounding 0.2PH and you keep adding acid like there is no tomorrow, my comment above is irrelevant. It is relevant though if you use a mild acid.

So you only need to acidify the water once and it only needs to go to around PH 2 max. PH 3 is fine. You can reach that with all mild acids.

Final recommendation, you can use the IFC calculator. It explains everything and how you need to mix the compounds and in which order.
