Yep tried mixing a few times and i tried to identify if it was a certain consentrate or the vg pg or nic i was using that was giving off a bad taste but never could. VG vaped fine on its own and with PG mixed then fine when added nic, but after chucking in flavours it always tasted shit! So i said fuck itWhen I first started mixing my own they all didn’t taste so good.. but 3 days steeping made a massive difference. 2 weeks is a lot though.
