Hello everyone I'm new to variable wattage and voltage and to sub ohms/cloud chasing I'm running a eleaf istick 50w with kangertech subtank nano .5 ohm coil and was wondering if there is a better way to find the sweet spot for me then just trying random watts and what's your preferred vape at mine is currently at 20.0 to 23.0 is that to high I worry I will use up my coil to fast at the wattage I'm using as I'm on a budget any information will be greatly appreciated
