I have no clue where to find hydrochloric or phosphoric acid where I live. Well I just have to search for it.

Check out pool shops for hydrochloric/muriatic acid and hydroponic shops for phosphoric acid (ph down). A 500ml bottle will last you forever they are pretty strong acids.

There are no pool shops around here but one that sells hot tubs around the corner. I'll check there. But couldn't I just go to a hydroponics store and buy pH down that's used for growing weed.
That should be safe for an acid cook if it's safe for the plants.

YES. Thats why swim mentioned hydro shops.

pH down will work, but is pricey compared to muriatic acid. They've got it at lowes and home depot and the like, you shouldn't have to go to a pool shop.

I found pH down that has phosphoric acid and nitric acid. Is nitric acid safe?

No! It's a reactive strong oxidizer and can give off toxic fumes.

Diluted sulfuric acid would be OK though, it's non-volatile. PH-down that contains sodium bisulfate NaHSO4 should be good, this behaves like dilute sulfuric acid.
