So I mix 50 gallons in my Top-off. Then, I move whatever fits into the plant sites after draining them.
I'm not very consistent though. Sometimes I'll mix my top-off to the desired EC and sometimes I mix it a little hot so that it slowly raises the EC of the plant sites.
I like keeping nutes in the top-off, though. I don't want to add to it every day. Plus, the only way this chart makes sense to me is if the top-off is the same EC/pH as the plant sites.

It all just depends on how I see my plants doing. If they seem to be doing fine, I'll have a hotter top-off. If they demand a bit more of my attention, I'll match them and try to diagnose what's going on via that chart.
I can go two weeks or more before amending my water. Sometimes I don't touch it until the top-off is nearly empty. I usually have 20-30 gallons after filling the plant sites. By the time they've sucked it dry, it's usually time for a res change.
