most folk will change it every 2 weeks or so
so you do not need to do it more frequently than that
personally i very rarely change it, i tend to grow larger plants the res is constantly topped up with water, nutes added when the ec drops a few points
find what works for you and repeat

i like to do as little as possible so if i can leave something out and it still works ill do that
i found that i do not need to ph them after the initial setup, i do add a little ph down when i start them off
as the ec is low at this point, i just try to keep them on the acidic side, the nutes are acidic so this is enough to do that
i know not everyone can do this with the ph and need to keep a tighter control on it (if they do not have good tap water)
i have a general idea what the ph is, i control it more by knowing what it should be at given ec ranges
but it must fluctuate between 5.5 and 6.5 and it works fine

I drain my rezs 100 percent, spray them down along with flood trays while draining every 7 days to keep it clean. I don't like guessing what the ppms of my water consist of. I like to know.
