the trouble with these options is that they are not as strong as true ph-up and ph-down and you'll probably have to add it to your solution more often.

Isnt that backwards? Vinegar is acidic and baking soda is a base?
Yes, there are substitutes, but as DO stated, its not as good as PH up and down, as solids can create buildups.
