May be measurement error. What is your Alk and what are you dosing?
During winter months with drier air, I find that my indoor CO2 drops as heat is escaping the house. Lower CO2 = higher pH.

A spike means what? An instantaneous rise is likely electrical interference.

In how many minutes?
Any pH rise at night when not dosing high pH additives nearby is likely inaccurate.

ATS's can raise pH, and lot's of people use them for that effect, besides the nutrient reduction, when operated on a reverse lighting schedule.
Do you notice if the increase in pH is moderated right after you clean the screen of your ATS?
