So my experience with rta's is limited to a few older models. I have previous experience with rdas and really enjoy them for their flavor. I have previously been using tanks with RBA decks or drop in atomizers. So here's my question. It appears as though with the rta's that the wicking darkens the juice considerably after a bit of use. I tried to stick with light-colored juices so my coils and such will last as long as possible. I know that's a darkening of the coloration is from the circulation of the juice through the coils and wicking. I guess I want to know if this is with all RTA? Is it just the rta's that I am using? And why doesn't it happen with the RBA Decks that I use? It is no tremendous issue it does not appear to change the taste of the juice and I do not allow my wicking to burn if possible. So is there any remedy for this? Or is it just something that I have to deal with? Sorry to seem like a noob here but I'm just curious. Peace and love from Sunny Clearwater Florida. Big Rick.
