Bad atty or bad juice?

[Blaze]

Quick question for anyone that can answer:

I've had for about 2 days a taste lingering in my mouth that can only be described as "metallic" and a sensation on the roof of my mouth and my tongue that can be described as "burnt" (sorta like taking a big swig of coffee before you realize it's still way too hot). In about the same time frame, I switched to a new juice. Would this be more indicative of a bad atty or bad juice?

Did you blow out the primer fluid before using the atty? It can have a pretty nasty taste and a new atty takes a few days to break in.

Yeah, the attys are about 3 weeks old.
