Once you have topped your system off with 45 gallon of water and extra nutrients, dump it all and redo it. I dont see 6 plants using 45 gallons of water every week.
Another example is my system. It has 6 netpots in a single 30 gallon tote. I made the batch of nutrients on August 29th. I have only had to add around 14 gallons of ro water total so far. I keep my ppms low, so im topping off more frequently than others.
As to the water left in the buckets, its fine. Just make sure you get all the sediments out of it before you top it off, if there is any.
I wont ever dump and refill my entire system due to having a larger holding capacity. I can veg for 2 months with this tote by simply topping it off. I can also flower for 2 months in my new system since it has almost triple the capacity of my veg.
Think of it this way, the larger your system capacity the less you have to do res changes. If you were in solo dwc buckets, you would be dumping and changing weekly during flower due to plant uptake, yet since your rdwc, you dont need to.
