where to get this formula

I bought the chemicals from the suppliers which supply to universities and college labs. Check my post in Roses in Soil-less medium, same chemicals are used.

complete names of elements

N (NO3-) = Nitrogen from nitrate
N (NH4+) = Nitrogen from Ammonium
K = Potassium
P = Phosphorus
Mg = Magnessium
Ca = Calcium
S = Sulfur
Fe = Iron

what is ppm

PPM or Parts Per Million is defined as Milligrams of solute present in 1000 ml water.
For example if we dissolve 5 gram of water soluble NPK in one litre (i.e. 1000 ml) of water the PPM of
the final solution after dissolving will be:
5 gram = 5000 mg
5000 mg in 1000 ml water
Ans: 5000 PPM Solution

Now to calculate the individual PPM of the components, we must know their percentages in the
compound. Lets say we have NPK 20:20:20, which means we have:

Nitrogen=N=20 percent
Phosphate=P2O5=20 percent
Potassium=K2O=20 percent

20 percent OF 5000 is 1000, so in this solution of 5000 PPM we have:
Nitrogen=N= 1000 PPM
Phosphate=P=1000 PPM
Potassium=K= 1000 PPM

how to mix them in how much water

You have to learn how much PPM of each element is required for the plants, there is a lot of information on internet. then by using the PPM calculations you drive the formula on paper i.e. how much any chemical is required in grams to be dissolved in how much water to attain the required PPM.

thanks for detailed answer

WHAT IS THE ADVANTAGE OVER CONVENTIONAL GROWING IN POTS?

No daily watering
No nutrient deficiency
Very high yield
Healthy plants

SIR KINDLY SHARE UPDATE PICTURE OF TOMATO PLANT THAT YOU HAVE GROWN IN KRATKY SYSTEM

Sure inshaAllah... now they are in bad shape because few days back they were knocked out by strong winds, now they are recovering but the leaves have burnt

Sir update please.......

Very bad shape, all roots were dried as the wind knocked it out of the container, I may start again:
