New vapor having problems

[Newvaper1997]

So I bought my first vape about a week ago. Spent around one hundred I have the Arctic tank and eleaf 50w. I bought a .2 coil and my friends has the same one. Today I noticed its hitting really week. I tried switching coils... The vape is charged and has liquid. My friend has the same exact setup and his is producing a lot more smoke then me. Same exact vape. Mine is spitting up Liquid, hitting weak and not making much noise. I switched between 3 coils and dripped all of them.

My guess it could be your juice is different than your friend's juice. PG/VG ratios can drastically make a difference.
