So I made a flavor that I love (vanilla cola) and I have vaped half of it. In order to "refill" it, I want to add all the ingredients in half (I made 10ml, vaped 5) So here is my question. I made it 24mg of nic using the ejuice calc. I have 60mg/ml nic. So my question is, if I added 2 more ml of nic, then the other 3 ml of no nic (including 1/2 the flavor I used the first time) , then that should make it 24 ml still? I know that 2ml of 60 mg/ml nic in 5ml makes 24, but I am not sure if when added already to a 24 mg juice what it does. I think that I am thinking it though to much, but I just want to nail my process down and I dont want to over do it with nic.
