you need to have enough water/gallons in rez to allow you to fill e&f table to desired capacity with about 5 gallons added for ppm control and evaporation/depletion control. You don't want your plants to drink the solution and run your pump dry.
So:
table capacity +
5 gallons= desired rez solution in gallons.

Use pure blend pro as directed, but monitor ph, because for some reason their accelerated bloom and veg formulas are not ph buffered.

It is kind of a trial and error method when you build your own. Keep a mop and bucket handy. LOL Hope this helps. Peace
