Fatty V2 Sour taste.

[zipthehuh]

Hello I am getting a very sour taste from my fatty V2 I am running 32awg wraped to 2.5ohms on a provari at 4.5 volts. I am using the 3mm silica that came with it. The are not hot spots I can see nor hot legs. I a vaping unicorn blood. which tastes fine in my carto's, hh 357, and cobra (can't get it to wick well but thats another thread). I have tried various voltages. The wick is also not burnt. I have it rinsed and drying to I can try a different juice to rule out the unicorn blood. but in the meantime I was wondering if anybody has ran in to something like this
