I have a Smoktech rda and Igo-L and I can't seem to use certain juices without them burning. The coil is 2.2ohm and I've vaping at 3.5v. It works great with darker juices, but with Gumby Blood and Ectoplasm from Fuzion Vapor, it just burns after even a small hit. They work fine in a tank but they do the same thing on both atomizers. I'm not sure what could be the problem. Could it be the wick(silica)?
