Made my first batch last week went well made three30 ml bottles one red hotcinnamon, bube gum, and a promo flavoring that came with my order they all taste good make great vapor but the one think don't understand the cinnamon one gets murky and then after a couple puffs it goes clear I let it sit for a bit and goes back murky the other two liquids stay clear no murkyness at all they where all made at the same time the flavoring are TPA is it normal? Is it dangerous because I've been vaping the daylights out of it I love it. Has it happen to some one else before?
