Juice HeadE Liquid Vape Juice 0mg 70/30 VG/PG 100ml (Peach Pear)

I'm unsure of whether there has been a chance to the ingredients or something similar, but this juice doesn't seem to vape properly, and is constantly leaving residue in my mouth, with an awful taste.I've had this exact juice before and it is by far my favourite one I've ever had.Sadly I bought three, just to "stock up", I'm unsure if the other two are just as bad but there is certainly something wrong with the current one I have on the go.
