Sometimes I think this issue is with how the cartos are being made (cheaply). I use Smoktech 3.0 Ohm and 2.0 Ohm single and double punched on Atemas Tanks and find that they flood frequently when going from an Air Conditioned House to the hot outside. As long as the temperature (possibly also the air pressure) remains constant, the vape is fine. If this seems to be your problem, I suggest when going outside, do not vape for several minutes to let the Tank and Carto adjust to the change. This seems to help mine. When this happens, I need to empty the juice back into the jar and just vape the carto with no tank until the juice is burned off, or blow it out (wastes juice but works), then refill and start again. Also keeping the tank more than 1/2 full helps a lot. I notice this only happens with a tank that is lower than 1/2 full.
