Bottled drinking water viable for plants?

Hi
I was wondering what will happen if I water my plants with bottled water?
Lests say you don't have EC/PH meter or ph upper or downer or RO machine or any other equipment that can test your water in any ways.
Since th ph of bottled water is the same on every feedIng (supposing u use the same brand every time) and the water is not heavy. Does that mean I should not be worried about the PH of my grow medium or any salt build up ?
Here are some info I found about bottled water. Or the brands I could find near me:
Most have a ph between 6.2 to 7.5 it's different with each brand but at a exact number
Most have some chloride , ca ,mg , na ,sulfate , floride , and nitrate. It's a bit different with every company

It will cost to much. Just use the water that comes out of the tap for the same results.

I heard that tap water might be too heavy depending on where u live in the world. Isn't that gonna lead to salt / residue buil up in the long run?
First grower and only gonna have couple of plants so watering cost is not that big of an issue.

Bottled water can vary greatly. In fact, some drinking water IS RO. If it says 'spring water' or 'mineral water' it is not RO and will contain all of the minerals above in amounts you will not be certain of with out a ppm meter and a pH you won't be certain of with out a pH meter. Without knowing mire about what type of bottled water you plan on using it is hard to say how it will affect your grow. Same with your tap water, there just isn't any way to know unless you test it. If you are using really good organic soil it will go a long way towards stabilizing your levels, but even the best soil can get all fucked up if your water is extremely high or extremely low in terms of ppm and/or pH. My advice? Unless you are a semi experienced grower with a good working knowledge of the soil you well be working with, you should get some meters, or at least test strips.

Let's say a well known brand like nestlé pure life. I think it's available in the US, Europe and over here in mid east Asia. I know the source of their water is different in different part of the world but the amount of additive and ph must be same I mean there is like a standard nestle drinking water or smthing that they need to maintain under the brand name. Anyways here is my question. Is the water with the characteristic below suitable for watering cannabis plant ?
All the amount are mili gram per liter. It's on the label of Nestlé pure life
Cal = 31.8
Mg = 6.5
Na = 1
Potasium = 0.4
HCO3 = 142.8
Fluoride = 0.07
Sulfate = 4
Nitrate = 3.5
TDS 147
Ph 7.2
I don't know the ppm or EC of the water

You said it all with, "First grower"

You're thinking too much, which is stressful, and wasteful of time. If your tap water pH is way off, consider adjusting it. I no longer bother. Fill a big something with water, keep dust away from it, but light it up, and let it breathe so the chlorine will dissipate in a day. After it no longer smells of chlorine, turn the light off to discourage algae growth.For small plants, or to encourage quick growth anytime, warm it slightly by adding some boiling water. When it feels warmish but too cold for a shower, it's right for plants.

Way too much thinking, just use tap water and once you successfully grow a plant you can decide upon whether or not it is worth the upgrade for a filter. But to use bottled water is just asinine.
