I did all that. Maybe I should explain a little better. Say you do the calculation for each flavour say 5% of a flavour in a 500ml recipe means you put 25ml of that flavour in and so on with each flavour your putting in total of 110ml of flavoring. Question is do you put 500ml of vg/pg like your calculations or do you just put 390 of vg/pg in to get to the 500ml. Does that make more sense?It’s simple yet very complicated at the same time..
Different flavour concentrates have different mix ratio a lot are 20 percent but not all..
Use the above posts mix calculator and read information on each of your flavour concentrates for the mix ratio percentage..
