Depending on its Pg/Vg ratio it vapes very differently, the more the vg the thicker the juice & vape , a thinner mix with more Pg is a thinner juice with a bit less vapor but to me, more flavor.My mix though is usually 70 vg-30 pg.
Well every hit I take with this thinner juice I get the taste and it's great, but a hit following that tend to taste burnt like their is none on the wick...that has nothing to do with the viscosity?
Well I think the thinner juice takes less to get it heated up and easy to over heat then you start getting the burnt taste(IMO) a lot of vapers who sub olm and vape for heavy vaper will use all VG juice with higher heat RBA's and rebuildable atomizers.
Just go down a little at a time to see if the burning taste goes away, what atomizer are you using? Depending on what you have, that may have something to do with the burnt taste as well.
