It's very easy to over smoke with an electric because the wood is smoldering. I have a Cookshack Electric that does't get used any more, but when I did use it I would use one piece of wood about the size of a golf ball and it was more than enough smoke for a brisket. Try backing way off on the amount of wood and don't worry about the color of the smoke. Unless the wood in there combusts and is burning with flames you won't get blue smoke.
