Hello all , i'm pretty much a newbie in vaping (also french so excuse my typos) and i recently bought a nautilus tank 5ml and i've had no issues with it for the first 2 weeks with the default 1.6 ohm coil that it comes with. Problem is today it started leaking crazy in the airholes and i guess under the tank,now it didn't seem to be too bad as battery was fine but even after cleaning it twice now it seems to be leaking still checked everything found nothing that seemed odd. Note that i'm now using a 1.8 coil as the 1.6 gave up recently and at the moment i tried to loosen up a bit the threads on both ends of the tank don't know if that'll fix it but until now it started leaking at about 3ml left both times. Am i doing something wrong or do i just have a dud ?
