    I am looking for a good meter that detects ph as well. Is this a good one at a good price?

    Some of the most highly rated meters at the hydro shop I work at are Hannas. I use the Hanna checker which is solely ph. Combo meters tend to be touchy and not last as long.

    Do you mix your nutrient gallon by gallon?

    or a large 20,50,100 gallon reservoir?

    i mix per reservoir which is 3.5gal each of water for 4 plants

    With such a small reservoir a ppm meter is not as important.

    Having a ppm meter helps, but if you are mixing 3.5 gals with under 4 products your ppm should be fine. If you have the extra money to drop go ahead, if not get a Hanna Checker and focus on keeping your PH in check.
