I am trying to create my own fertilizer and took the advanced nutrients Grow part A and Bloom part A as inspiration. After lots of calculations I came up with a mix of salts whith a composition that resembles that of Advanced Nutrients. But i am left with two questions. 1. I could not get the right amount of K. Instead of 12% in Grow and 11% of Bloom i have in both Grow and Bloom 18% K. Does this have adverse effects on the performance of this fertilzer mix? 2. % is the same as gram salt/100 gram solution. So 9% N corresponds to 9 gram N/100 grams solution or mix. The total for both mixes is in the 90 grams so there is only room left for about 10 mL (10 grams) of water. This is not enough water to dissolve all the salts. At what PPM is undiluted Advanced Nutrients solution? This is how I calculated the recipes: Percentage of the elements in the fertilizer salt are columns in a matrix. From this a system of equations is solved For Grow Part A For Bloom Part A In the matrices MgNO3 = Mg(NO3)2. I made a typo This resulted in the following recipes. Both the results from the matrices and in the table below hold since x8, x9 and x10 are variable. Which is compared to Advanced Nutrients. Only Possaium differs And a reference from Big Mike
Maybe this will help you to understand nutrient interactions with each other. Playing By The Rules : Biochemical Sequence, Nutrient Antagonism
Very interesting. Make sure that all ingredients used are compatible with each other and won’t cause a negative reaction once mixed. also you are probably ahead of me in this regard but don't forget to remove the unwanted elements in your calculations for certain nutrients. Example, for Boron; Na2B4O7, you would have to remove Na2 and O7 and their atomic weights to find the actual amount of Boron in the mix. Vice versa.
Its definitely one of my favorite knowledge finds. It will either confuse and confound people or it will cause them to take their grow to the next level of understanding. I spent a year trying to use individual nutes from NPK Industries and it didn't go well. I was use to FoxFarm nutes with pre-determined ratios in each product. I wanted to dial in on the best possible ratios for marijuana. I did two grows with the NPK and burned the hell out of my plants for 2 grows. It was quite a setback. I have since gone back to my tried and true FoxFarm liquid and water soluble trios, with Botanicare CalMag Plus and Alaskan Naturals Micronutirients. With everything I've learned about the antagonistic and synergistic properties and interactions between nutrients, I've been able to maximize the efficiency and effectiveness of applications I provide to my plants.
Well these ratios are the ones from advance nutrients. Just have to keep the solution below 2000 ppm and it should be pH corrected to 6-7. Then there is no nuteburn And you have to keep in mind that other stuff is also added like Voodoo Juice, Bud Candy, Nirvana, etc without going over 2000 ppm I read somewhere that Potassium levels have there sweetspot at these levels. N:K = 1:2-10 Meaning that i'm in the sweetspot with potassium. Even without being Exactly the same as the levels in Advance nutrients. The antagonism with Ca and Mg can be solved with Part B. But this wont be necessary probably.
So I think that I have figured it out. Afer 20/30 years of research Advance Nurtients claims that these are the ideal ratio's for cannabis fertilizers. So this corresponds to the following values: Grow N-K-Ca = 7-6.8-3.6 Bloom N-K-Ca = 8.4-8.8-2.6 To achieve these number Part A and B are combined. Grow Part A (Grow) = previous mix, N-K-Ca = 8-18-0 37.78 grams of Part A + (2.69 grams of NH4NO3 + 19.46 gram of 5Ca(NO3)2.NH4NO3.10H2O) = Part A + Part B = Food for plants, N-K-Ca =7-6.8-3.6 Bloom Part A (Bloom) = previous mix, N-K-Ca = 9-18-0 48.49 grams of Part A + (5.16 grams of NH4NO3 + 14.05 grams of 5Ca(NO3)2.NH4NO3.10H2O) = Part A + Part B = Food for plants N-K-Ca = 8.4-8.8-2.6 So you dissolve Part A in water and part B in water and add them together and dilute it to the proper concentration
