After reviewing the literature from the links posted and some googling, it seems that the mA flowed during the CS generation determines the time of electrolysis (15mA × 1min = 1mg Ag, thus 3mA × 5min = 1mg Ag, or 15mA·min = 1mg Ag; I'm not sure how true or accurate this rate is), and this mA setting is also loosely dependent on how well the solution is stirred during the process. A higher stir rate keeps solution concentration more uniform and if a higher current is used the solution could have a greater local concentration between the electrodes compared to the rest of the solution, which could result in bigger particle size than wanted (<-- why they say to increase stirring at higher currents I'm hypothesizing?).
Ag particle size seems to be of interest by the majority of amateurs, but whether the size needs to be large, small, or ionic seems to be majority contended. The academic studies show that ionic Ag is actually the most anti-microbial form of Ag. They also seem to suggest that the AgNP (silver nano-particles) mode of action is very similar to the ionic Ag and that this is due to the AgNP's transforming into Ionic with time ect. I've not been able to find any academic studies on Ag and plants. So perhaps a larger Ag particle size is wanted for MJ hermaphoditism, but all I could find on the topic was forum based and only MJ forums. The academic world points to ionic as the main beneficial form, but that's with humans and antimicrobial in mind, so I can't really give an opinion on Ag particle size when it comes to forcing female plants to hermaphrodite.

I did read up that the most common method described is not creating a pure AgNP mixture, but it seems it's some sort of bro-science. This is the adding of Sodium Carbonate and Corn Syrup method. (See link below)
It looks like maybe you could repurpose and recalibrate your pH pens to determine Ag ionic ppm. You could use your TDS meter but you'd have to deduce the EC reading from the ppm (EC = ppm ÷ 500, or EC = ppm ÷ 700) and multiply this by 1.1, and best case scenario would be 10% - 25% off. But as far as AgNP or suspended Ag particles, a laser with a photodiode measuring the intensity of the Tyndall effect would be a pretty accurate way to determine size of suspended Ag, or AgNP size, and a ppm of AgNP's, or suspended Ag particles, could be deduced from subtracting the ionic ppm from the total ppm derived from a Nitric acid wash followed by a HCl wash and filter process described in the link @timezone added.

Posted 4/7/2015 - making ionic silver and thinking its colloidal silver
Hello Mike, Here is a link I recently found on the making of Colloidal Silver. This guy seems quite scientific in his approach to making the colloid. He seems to have some background in electricity and chemistry or both. What I hope you will tell me, is what he is doing sound? He never...
