How can I have a less acetic sourdough starter for pizza ?

I have a sourdough starter im currently making i am feeding it whole wheat flour. I want more of the other flavors from sourdough not the sour taste. Should i have a higher hydration or something ? I saw on youtube you can reduce the sourness by increasing hydration. Im a noob so i dont know where to start.

I use a white flour starter at 100% hydration and I hardly ever get any sour taste.  Don't go too low in the refreshment ratio (use e.g., 1:3:3 starter:water:flour) and don't let it age over long before using.  For example, if you had a starter that took four hours to double but you refreshed it only once a day, then by the time of the next refreshment it would be pretty acidic.
