Big difference between moist and soggy AFA root rot.
This will come from experience, yours, there is no schedule or timetable except what you figure out for your particular plants/mix/set up.
If you know your plants well, water when they start looking a bit *wilty* from lack of water. If you can't tell this, wait till they actually wilt (counting days), and then water one day sooner.
Remember, mycos in nature don't get rained on with any sort of schedule and still manage.
