increased to 1400 ppm strength solution ?
 

dear ron,

i have a question which has been in my find for some time now. you see, i received a recommended micro nutrient and macro nutrient combination which if you add them individually is at 700 ppm.

now, how can a formula with 700ppm to increased to 1400 ppm strength solution ?

does it mean i have to increase N by one fold and the rest of the macro and micro nutrient elements by same margin ?

You add each one the same amount in percentages to increase ppm.
If your mix calls for 1 teaspoon of macro and 1/2 teaspoon micro and you need to double your ppm then you would add 2 teaspoons of micro and 1 teaspoon of micro.
