Easiest and cheapest thing to test first would be simply go to your local supermarket/grocery store and buy a FRESH/NEW bottle of distilled water (don't need much as you know), that would help rule out your 'car battery water' as a problem, and more often than not it will be impure water causing problems
like a yellowing or "wine" or "tealike" composition of the water.
Afterall, if your .999 silver really is that pure then the 0.001% impurity shouldn't be large enough to cause an issue, and .999 is what myself and many here have always used (there is no need for the extra expense of .9999).
It really needs to be just pure distilled water though because you don't want any other silver compounds being created via the electrolysis ... if you use tap water for example you could end up with silver chloride and silver fluoride (etc)
... probably not good for the plant, and probably not good if somebody ends up smoking any of that plant.
I'm not a chemist, I'm erring on the side of caution. I consider any plant sprayed with CS (even if just one branch) to be a "non-consumable write-off" -- all i want from it is the feminised pollen.
Distilled water is cheap (not quite as cheap as drinking water but we don't need much of it) and easily accessible so there's no need to gamble wasting your time with anything else.
