Watering with carbonated water?

So let me know if I'm talking madness, but here's the question: If you were to water a garden/lawn/flowers with carbonated water during the daylight photosynthesis phase, would this be better than watering with just plain water? If so, does the mechanism have to do with delivering more CO2 to the soil, which the plants are trying to uptake in this phase, or does CO2 uptake not take place in the roots, but at the leaves? If this is not a beneficial thing for plants, why not?

This is probably not a good idea. Carbonated water is more acidic than regular water because it contains carbonic acid and this will decrease the pH level of the soil. Changing the pH like this could be harmful or deadly for the plant.
