Yup, the hydro stuff is what you want. A strong acid such as hydrochloric or even better phosphoric is the most efficient way to lower pH without adding metals, since the cation in these compounds is just hydrogen. Same way you want to use a strong base to lower it, since the anion is -OH and won't interfere with your other ferts.
Hydro up/down is designed for minimal interference with ferts.
