I personally have not experienced the green juice problem yet. Can you tell us where you purchased your gear from? What country are you in? First thing, I would contact the vendor you bought from, then I would change tanks, atomizers, etc. Take pictures of the green liquid and the drip tip showing where it is and leave it alone until you can get a reply from the merchant. It does sound like food coloring in the eliquid or maybe the atomizer is not a genuine product from aspire. Until I found out, I would not be using it. This is only my opinion, but then who wants green ejuice in your mouth when you can't id the source.
