you're thinking of sparkling water. mineral water has no co2. don't use seltzer water. i believe it has salt in it. i tried it years ago, but didn't see much reason to continue. just make sure there's plenty of fresh air available to the plants and they'll be happy. or step up and get a co2 system. good luck with the babies!

I have been using tap water a few decades , along with ph up and ph down, fertilizers.
Check if your mineral water has the proper ph an ppm levels. N-P-K levels for fast growing with soil or hydro. A good ph and ppm meter is well worth the money.
If you want to save money do some more reading on the subject it will produce more bud for the buck
Now mineral water and seltzer water will work best with a good burbon, or scotch even rum.
Your plants will tell you in 3-4 days what to add, usualy I get 2-4 inches a day depending on the strain.
Ferts are the cheapest thing about growing, lumen/watts and last time

In my experience...not necessary.
If used as a foliar spray, it dries to a sticky mess, and clogs the pores in the leaves.
Also can attract insects like gnats, ants...

Keep it simple, till simple doesn't work.
