The "smoke" that you read about, if you shine a light through the cell and see long wispy "arms" of cloudy solution (a.k.a. "smoke" by analogy) coming off the anode where they kind of linger or meander around some, you need to drop the current you're running at as its too high for the surface area of the anode you're using.
What you're seeing is silver oxide being pushed off the anode that has yet to dissolve because its being produced too quickly by too high a current. It may dissolve, it may not but seeing this, you're either borderline or over the wire and really need to back things down until you stop seeing it and then back off another milliamp or two or three for some wiggle room.
The bubbles around the cathode are normal, expected and what you WANT to see.
Anode "smoke"? NOT!
Sometimes I see it but then look closely and find that there's a lot of bubbles attached to the anode wire (no clue why because they weren't there right before I started up the cell) which are effectively limiting the surface area on the wire in contact with the water where just tapping the connection to the wire outside the cell creates enough mechanical vibration to knock them all off and everything returns to normal and this doesn't happen again during the run. This doesn't happen often but I have seen it more than once and am still perplexed as to whats causing it and why. No, I'm not stirring - just letting the convection current in the water from the container being bottom heated, keeping the water at 150F, to keep things in motion.
