So I've been making my own e juice for about 2 weeks now. I've been toying with different flavor combinations and there's one thing I can't figure out. I have a total of 5 flavors so far and every single one of them tastes funky. It kind of has a beer/alcohol taste. That and it seems like the nicotine is way higher than I want it to be. I vape 3mg/ml nic and my juices hit way harder than any 3mg I've ever bought. I use "e-juice lab" (app) for all my measurements. I was just wondering if anybody knew what the problem could be? (Bad ingredients, false measurements, ect.) I can't figure it out.
