Wow everyone thank you all for the ALL the information. I really want to find something better than ECBlend. I don't mind spending a bit more to get more flavor and for the juice to have more consistency from bottle to bottle. I love their prices but I got too many flavors that had that cheep primer taste. They came from 2 back to back orders. I will keep getting the Peach Watermelon Cantaloup from them for now.
See, here is my observation and it is just speculation (This does not include the 2 bad batches that tasted like primer). I think that the base in the juice (PG or VG) has a smaller size molecule than the flavor or sweetener. I love the Peach Watermelon Cantaloup when it had darkened up in my clearo a bit. I can vape it when its newly cleaned if I fiddle with it and loosen the cap and loosen it on the batt so it wont be so hot. But it takes a long time to get both ends of the clearo just right and by then its time to take it off the batt and open the fill end for another refill causing me to have to start over again.
I have switched over to CE3's and I get more consistent taste but its not as good as the sweet spot I was getting with the clearos but the juice killed the clearos too fast and I spent another week or so using a somewhat clogged clearo since they were so expensive chasing that sweet spot. With the CE3's I get a dryer harsher vape that the juicy sweet spot I could sometimes get with the clearos.
I am thinking that if vendors tried to match the molecule size of the base to the range of molecule sizes of the flavors they are creating it would also improve the quality of the juice in many aspects. Its just my own hypothesis...
Try pulling the posts up a bit inside your CE3s to improve juice flow/wicking. They should not taste dry.
