What you're doing is raising the pH to compensate for the natural lowering caused by yeast activity during fermentation.
A better approach is to measure the pH with a meter (they're cheap) before you pitch the yeast. Adjust the wort as necessary with acid (backset or lemon) or base (your pickling lime) to get it between pH5 & 5.5
Then pitch the yeast.
