Natural minerals solution
I want to know if there is any other mineral solution to make for KNF, that is besides diluted sea water, for example a natural solution with rock dust. an d if so how I go about making it.

Cho has not taught the method for making the minerals outlined in his literature. He has said that a lab in Japan has the recipe and also produces it. Largely under testing the minerals vary widely from batch to batch and there is no consistency in the process or product. At one point I heard him talk about the alchemy of the process and how precious metals were involved, which led me to believe that it was some sort of consummation of the union between two rocks.
The way to make minerals in a home brew sort of way is to create a bacterial mineral water machine. The key is to load the machine with different types of rocks with sharp edges so when the falling water hits them, the minerals will be pulled into a solution. The official machine drops the water from 3 meters which puts enough acceleration into the water to really bludgeon the rocks, and as the water falls it tumbles and sucks in oxygen which also assists in the dissolution on a chemical level of thinking.
This youtube playlist has a lot of videos on the mineral solubilization machine.

Drake's mineral input is diluted seawater. Every element is present in the sea, and dilution to the salinity of blood lets plants absorb them. (Cho's Solutions, p. 1)
- Fresh seawater: dilute 1:30 with fresh water. (Cho's Solutions, p. 15)
- From sea salt: 1 gram per liter of fresh water. (Cho's Solutions, p. 15)
- Large batch: 120 g sea salt in 30 gallons of oxygenated water. (Pure KNF Manual, p. 53)
- Dissolve the salt in the water, then drench deep into the soil. (Pure KNF Manual, p. 53)
One JADAM fertilizer step pairs seawater with phylite minerals, diluted 30 to 300 and irrigated into soil. (Office Hours Ep. 142, 50:42)
The library gives no recipe for a rock dust solution, and it does not say what phylite minerals are.

Thanks a lot for your answer, I am new to this subject of KNF and are taking the time to make all the solutions, before I start using them in my land. I consider your answer is the best you can give me, but is a shame Master Cho does not have an easy method to use rocks or rock dust, as does JADAM.
Thanks again for your prompt answer, I hope I can share my progress with you in the future.

I make cheese and has excess whey. This is very acidic. I add a pouch of rock dust to it and stir from time to time. With the increased surface area of rock dust as well as the acidic environment of whey, it leaches minerals to the water. I then strain and use the water in my aquaponics, wicking beds and garden.
One idea is to get rods of different metals from the internet and using a colloidal silver machine, electrolysing them to leach the ions into the water. It would be hard to get the diverse metals though.
Still, I think using rock dust is a better option as it provides a diverse range of minerals and ones there are enough worms in your soil to process it.
Another option is to mine the minerals using tap-rooted plants like dandelion, comfrey, fennel, milk parsley, sea holy, coltsfoot and preparing a weed tea using these plants.
Diversity is the key.
Thanks a lot for the answer, it has been very helpful and practical indeed.
I use granular horse feed salt, it is loaded with minerals and super cheap, mix it to seawater salinity and use as such
