The increase in conductivity with increase in silver ions
occurs only in a very non conductive medium, like distilled
water.
In a very conductive ionic medium, like citric acid
solution, silver ions replace hydrogen ions, in the
solution, and are less mobile than hydrogen ions, so the
conductivity goes down as silver replaces hydrogen.
But the citrate ions balance the charge of the silver ions
and allow a much higher concentration to be stable, without
forming clumps of neutral silver atoms. I think.
Chemistry is not my area of expertise.

The only risk would be producing silver ions in a citrate
solution to a very high concentration of silver, which is
possible, since the citrate ions electrically balance the
silver ions, keeping them from forming neutral silver
particles. "
