Problems with N-P-K ratios

Alrightt so i know what that ratios on fertlizers mean and all that good stuff but what i reallly do not understand is how do you add npk ratios? For example im using as if right now DNF bloom A and B with DNF bloom fortifier for the extra P and K ratios, but the ratio for the part A is 3-0-3 part B is 1-0.5-3 and the fortifier is 0-50-30 so what im assuming is just add those numbers together and thats about it... But i know that cannot be the right math i want to have my ratio around 4-8-6 but i really need to know how to add those ratios, and im not exactally sure but 0-50-30 seems to be a preety big ratio for marijuana but could i not just dilute it? But also how would the math work for that ? Any advice at all would be amazing

Also additinal information of the nutrients is, it says on the fortifier 5ml per every 22l of water and for the part A and B it says 5ml per every liter im just really lost in all this math stuff


short version: my ratios are 3-0-3, 1-0.5-3 and 0-50-30 and i want the ratio to be around 4-8-6 how do you do the math to figure out how to add the ratios or whatever math it is for it or howdose it work?

The ratios are based on percentages. If you use equal amounts of each you can add them all up and the divide by the number of parts you added to together (in this case 3) If you are using different amounts then you have to use fractions to account for the different proportions. You know basic Junior high word problems

Ohh alrightt so for the A and B just add the ratios then divide the ratio by 2? 3-0-3+1-0.5-3= 4-0.5-6 then divide 2 by each ratio? Ive always been just horride at ratios... But with the other nutrient how would you use fractions with ratios

lol time to go back to school c'mon man

Im pretty sure i got it but thanks
