When I originally set up my wick and coil a week ago my meter read 1.3 ohms and was in vaping bliss throughout my battery life. Today I noticed I wasn't getting a very nice vape when my battery hit 3.5v. So I cleaned out my tank with some tap water and dry burned the wick and coil. I then used my meter to check the resistance and it has jumped up to 1.7 ohms. Is this rise in resistance a normal thing?
