Mike, I may have a partial answer to your problem, but we use very different set-ups for making our brew. I use a silvergen SG-6 with different electrodes than standard. I made some copper electrodes using electrical copper wire (very pure-about .9995) just for a lark. I experienced a very strange phenomenon. The SG-6 is current controlled to about 1 mA and has automatic shutoff at about 6.5 volts at full setting. At least it does with silver electrodes.
Here's where we get into the twilight zone! With the copper electrodes everything proceeds as usual until I get to about 5 micro-seimens on the PWT. The CC is colorless and has no Tyndall effect. This occurs at about 17 volts.. From there on the current remains constant AND the voltage remains constant! The brew begins to take on a distinct copper color and has a very strong tyndall effect! Apparently, the setup makes ionic copper to a certain voltage and then suddenly shifts into making only colloidal metal particles! (It did not prove to be stable). I don't know what happens with a constant voltage low current density method such as you use, but perhaps this will offer a clue, since it seems copper and silver behave very differently. Hope this helps.
