Help me make my own nutrients please!!!

Hi everyone,

I have found a farming company that offer the following products:


Please can someone help me make a nice mix for VEG and then another for bloom.


The best however would be if someone explained in more detail what each chemical is for so I will beable to make my own mixes too.

Thanks guys!

Check out the thread in my signature. A lot of those recipes at open-salts weren't reverse engineered very well. Use at your own risk. For example, he forgot iron in at least one of his mixes (death), and assumes that it doesn't matter what salts he uses as long as he ends up with the same NPK. This fails when a manufacturer uses something like nitric acid for a specific purpose and he replaces it with ammonium nitrate. (because ammonium nitrate raises N without raising Ca, it must be exactly the same as nitric acid.) I'm looking at Flora micro hard water in particular. I already brought to his attention that their MSDS says it contains nitric acid, but he told me it didn't matter and left his recipe to not include it.

A few things.

1. I fixed a lot of the problems you brought up a long time ago. I accepted that the first attempt I made wasn't perfect and I fixed it. I'm sorry you couldn't let that go. I accepted the fact that I was wrong and I fixed it.
2. Flora Micro Hard Water does have an iron product in it. It's not my fault you never bothered to see if I made any changes.
3. The reason it doesn't matter that much is because an NO3 ion is the same whether it comes from nitric acid or calcium nitrate or ammonium nitrate. There are many different variations of a calcium ammonium nitrate double salt on top of that. The most common is the blend used in Yara Calcinit and any other 15.5-0-0 +19Ca product. Adding to all that the wide range of nutrient concentrations plants can use or deal with, you'll find that it doesn't matter that I didn't use nitric acid.

I think you miss the entire point of a hard water formula. Using calcium nitrate to provide all the nitrates would mean having higher than intended calcium and defeat the entire purpose of the formula. The point of using nitric acid is that you will need to use less calcium nitrate to compensate for all the calcium carbonate in the tap water.

You're going to need a strong acid regardless of nutrient requirements. That's what it means to have water hard enough to warrant using a hard water formula.

If it doesn't matter... why is that the difference between the 2 formulas? (hard and not hard) General Hydroponic's chemical engineers were stupid and didn't know any better?

So when reverse engineering do you have an analyzer that checks every chemical and/or micro nutrient and % or do you call the company and ask them what's in it or go by rumors from ex employees??

He's going by the labels and the msds. It's not exactly a mystery what's in those bottles.

Where'd the fertilizer database go?

It disappeared.

I managed to print out the pages though

I use to do this until I realized I was using 14 different salts to not use 14 different liquid salts that are easier to mix.

after too any trail and error and inconsistent yields

I just use a full nutrient line up that is designed for cannabis

Well that is exactly what I want to do, make my own nutrient solution designed for cannabis, I am not going to make one designed for tomatoes!

Anyways I have managed to find a nice program that allows me to copy formula's and then it tells me how many grams of each chemical to add to water to make up a Micro, grow and bloom mix.

See the image below, it has the heading : Substance name , and then A and B infront of each chemical.



A and B:

From the reading I have done I understand it like this:

Certain chemicals "react" with eachother, other chemicals dont react with eachother.


You DO NOT WANT the chemicals to react with eachother, otherwise it could cause a chain reaction ending existance itself.

Instead you mix the chemicals labeled "A" with the other chemicals labeled "A" - These guys dont mind being mixed together.

Then the B chemicals can get mixed with the other B chemicals, they also dont mind being mixed together.

Thats it, that is your stock A and B solution...

I will be mixing my fertilisers up soon, and I will compare clones with my mixes VS other brands of mixes etc...


I have always been interested in science as a kid...and this is so exciting mixing my own chemicals!


I am going to get some 5L glass beakers so I can use a small flame thrower to heat the solution up - 100F should do the trick. This should help the salts dissolve in the water.

The above ratio's are used for 50L RO/ Demineralised water.


Apparently sodium benzonate should be added as a preservative.

You could always just pee on them

So what happens if you mix A & B together?

If you mix them together in their undiluted forms, then other elements will be created that are bad.

When you mix them in water you first mix part A and then you mix part B. Then they don't react with each other.

In other words, you couldn't figure it out. Instead of seeking help, you decided to share your opinion here.

(because clearly the people who don't get it have opinions worth considering. (blind leading the blind))
