Tried a new vendor juice today

[whoaitsruss]

So I usually stick with one vendor juice they have many different flavors there juice is 70vg30pg... With that being said I wanted to try a new vendor juice they were 50/50 and just wanted to see the difference in throat hit vapor and flavor.... I actually enjoyed it... This was going in my rsst and when I was done with the tank I opened it and wow everything was black... Is this that common in sweet 50/50 blends or with just certain vendors
