Hi, I just started using a smoktech rda mini & the wrap is good on it. It's 2.15 ohms & worked just fine until I took it off my battery & then put it back on again. The draw is really tight on it now & I'm not sure what I should fix to stop this. The air hole is still right next to the coil & not covered up. Not sure what's changed that's caused the tight draw. Anyone have any thoughts?
