I'm new to vaping. Bought an I stick 50w with a freemax starre tank. I'm using the .5 coil but don't really understand the ranges for the .55 and .25 coils. What is the max-minimum wattage on them? I'm also searching for a flavor sweet spot when it comes to juice ratios and wattage. Like is it better to go with higher/lower wattage with more vg/pg/nicotine?
