I set my pH and water straight away, then I know it's correct going in. Never checked a few days later, but then I've not had a problem. To be honest once I get going I don't check pH or TDS unless I make nute
changes, I'm so used to my setup.
Think after this next run il give those auto pots a go or even the blumats. Would be lovely to have a set it and forget it grow.
