Hush is an OK vape for me, not outstanding, but nice every once in a while. The trouble I'm having is that every clearo I try it in, it turns black as tar...Vision Extreme, Fluxo deluxe, Stardust, Phoenix...all of them. Anyone else having this issue? It seems to burn a bit after it turns colors, and I have to dial down the voltage or it gets pretty harsh. (The highest I go anyway is usually 3.7-4 on a Twist).
