icic, thanks for the info, but how do i switch to a looser cotton ? because i aint using a dripper. would u suggest me to recoil it to a smaller radius ? like lets say 1mm ?

Tighter cotton or looser cotton has no correlation to the size of the coil.
It simply refers to the amount of resistance you feel when pulling the cotton wick through the coil.
If your cotton is too tight, it restricts the juice wicking thru the cotton, so you get burns. A looser cotton wick will allow easier and faster flow of juice, so it won't burn so easily.
A 70%VG juice is quite thick (when compared to a 50/50 juice), so the wick has to be a bit looser than your current build in order for the juice to flow fast enough to avoid burnt hits.
Just use a bit less cotton than what you would normally use; you'll have to experiment to see how much cotton suits the juice viscosity in that particular build. Also if your atomizer has juice flow control, open up the juice holes a bit more.
