Question on topping off res tank for ebbflow system.

I flooded my 3' x 3' ebb flow system yesterday for the first time. I have clones and they are all young. I was wondering how often or much do I top off the tank with plain PHed water? Everyday? Looking at the PH meter last night the PH has stayed the same and so have PPMs so far.
I am using Rockwool cubes. Thanks for your help!!

I top mine off when needed! I add A gal to 3 gal everyother day... Your room temp's will also make A diffrence.
