Update: after re-reading shen's post i checked the connections. One of the screws on the positive block was loose. I tightened it and both coils are firing. The problem with vapor production has been solved. The flavors still kind of dull and the vapor isnt as hot (using the same juice). This leads me to believe (correct me if im wrong) that my previous build was with a different gauge wire and simply heated up or "ramped" up faster. The old build was a much hotter vape with a way harder throat hit, once the button was fired the juice heated up and spattered much more violently if im describing it correctly. If im correct please recommend something to that nature. I currently have 24 gauge kanthal but can pickup whatever is needed. Thanks for helping me out guys!
