I think the PH is to low for it to have any useful effect. I just tested some diet tonic water and it was below 4.0

I would also make sure to get the stuff that desn't have quionine in it. That stuff can't be good for plants.

I was a big fan of Hydrogen peroxide.
If your growing in dirt you can use 20ml per gallon of 35% peroxide.
it will fizz-up the root zone with oxygen.
