A water change
During the cycle period, the chemistry in the tank will be quite caotic. The acids produced from rotting susbatances is constantly pulling down on alk
and pH. Once the cycle is done, the chemistry can be corrected. If you where cycling with freshly harvested and/or life encrusted rock, I would suggest the water changes during your cycle but that is not the case.
If after the cycle and the necessary water changes to lower nitrate the pH does not correct itself, you would need to look for environmental causes. For now though I wouldn't worry too much about it.
