To be honest I'd leave it be while I was gone. You can teach your wife to dose if you want. Maybe you should invest in a liquid doser, Big Al's has an inexpensive one, but you won't have it available for this trip.
When your ferts arrive, give it the N and P, and let her dose the other stuff while you are gone. When you get back, pick up where you left off on the N and P since those are the two you really want to be there to watch.
Aquascape? I'm a crypt farmer.
It's a fine line between fishing and standing on the shore looking like an idiot.
That IS an aquascape, it's titled "The Vacant Lot".
