I started with BWB Casablanca and decided to try out BWB Blend so I bought another tank (same brand Smoktech) and some 3.0 dual coil carts (also smoketech) , but I had to move my voltage up from 4.8 with the Casablanca to 5.8 with the BWB Blend to get any sort of throat hit or cloud production and I can only manage to get three puffs before vapor production and throat hit go down to almost nothing. Is it the juice or did I kill the cart?
