Just ordered 4 different flavors of e-liquid from the same manufacturer. All of them are 60 pg / 40 vg and 6 mg nic. 3 of them vape great, but the 4th seems to give me a burned flavor way too easy. No scatchy hits or throat pain, just a burned flavor. I have to turn to power down from the typical 18 watts to 14 watts to decrease this. Even then, if I hit it for too long, I get a burned flavor. This is in a Subtank Mini with the rba deck at 1.2 ohms. Any ideas?
