hey guys, I recently bought a smok Nord it was great with in the first 24hrs but since then I have noticed I am having to suck a lot harder to get a decent vape, or any vape at all for that matter. I have tried to change the coil to see if that would make a difference but it hasn’t. I am using the 0.6ohm mesh coil with 70/30vg/pg. Any one got any information on what the could be please? TIA
