I have a bottle of 30/70 pgvg no nicotine 250ml and a bottle of 50/50 pgvg 12mg/ml 1000ml 30oz. The question is that I bought the 30/70 thinking it had nicotine in it which I see now doesn't. I want to make a 10 ml bottle with 12mg nicotine somewhere between 30/70-50/50 so the bottle with out nicotine doesn't go to waste. Is there a way to use both of those together or am I out of luck. Plz help anybody.
