Reading your post above about your setup, I thought this might happen. Everyone has a different experience so by no means am I trying to dictateI've just noticed with my Aqua I'll get dry hit and burnt spots if I go lower than .7Ω Right now my Fogger V4 is at .784Ω with a dual 9/10 wrap micro of 28ga.
I don't doubt that at all, I just happened to hit .5 when wrapping, and didn't feel like wrapping two new coils. Since I can't really taste anything right now anyway, I'll just finish this tank off and then see if it is actually burned. Probably be a good idea to open it up after the first tank, to see what is going on in there.
