Ok so lately I've been having some problems with my vape and e juice. I use a 50w Ileaf istick with an Atlantis tank. I on vape 6 nic juices and lately they've became dry and harsh. First I bought a few new flavors to try and they were so dry and harsh that I couldn't hit them anymore, so I went back and got a juice that I've had before and knew it wasn't dry or harsh, but once I vaped it, it was just as bad. I tried replacing the coil, cleaning out my set up and some different flavors with no nicotine and nothing has worked. I've also not been able to get as big of clouds as I could before this started. I've tried turning up and down the wattage along with turning the air flow up and down. I know this juice is not suppose to taste like this so I'm assuming there's something wrong with my vape ??
