How often do you spray?
Incorrigible!... no need to pH, but I'd use low ppm water, like distilled, RO,...
....yes, lights on, that's when the stomata are open and taking in CO2, releasing water vapor, etc.,... Plus, direct light will force drying faster (less time to absorb), and if there's stuff besides water in the spray, it can potentially cause a sort of burn,... for a simple rinse this isn't that critical, but you should know either way,....
Go to the Reference section and read up on VPD, vapor pressure deficit, and how this related to transpiration... there's a good video link too that explains things! This process is one of the Kingpins (pH in-pot or res' is another) to everything else going on in the plant, you don't need to be a botanist to get the gist and see why and how it links things together,.... T and RH% are far more important than many folks realize!
