Im new just finish my first combo flavoring e-juice stop by the local vape store the other day and talk to the guy who mixes there vap and he told me a little trick on like lemonade pink lemonade any citrus tang flavor but I didn't know that I could go to Walmart and buy citric acid mix a small bottle add a drop or two a flavor and get that sour power punch that was needed and lemonade so I guess what I'm asking is if any other diy makers have any tricks please do share
