With carto tanks becoming more and more popular I'm wondering if anyone is experiencing your juice tasting different as the tank goes down.  I just started using the syringe tank and it holds a whooping 7ml.  I can fill it and vape for 2 days... which is good buy maybe not so good.   By the end of the second day, I've noticed what juice is left is darker.  I'm thinking that prolonged exposure to a firing carto can "cook" the juice so to speak, or at least change some of the composition.  I don't know that I'm noticing a drastic change in my juice's flavor but when I just filled my tank, I took a syringe and sucked out what was left (about a ml) and filled with fresh juice and notice it's tastes a bit fresher.. lighter maybe.  
Any thoughts on this?
