perhaps to clarify - one thing about maintaining a reservoir is that the PH typically goes up, maybe this kind of interaction is what you are thinkin about OP. Like the solution is always changing, reaching some kind of equilibrium or something after we fucked with it (no idea).
So when growers set the ph to 5.6, it's kind of expected that the ph eventually goes up, maybe even to 6.2. And the EC changes too, I dont know too much about that. In my case the ph goes up and EC goes down slightly
Those are maybe some of the interactions that you are aware of, but don't really matter to most of us, because keeping the water good enough
for7-10 days is not difficult.
& Finally, dont take people's comments as looking down on your light, just keep in mind that less photosynthesis means there's not as much need for all other things required in the process (water, nutrients, etc)
