Question

EI fertz and smaller water changes


Is it possible to design an effective EI dosing regimen in which you perform a 25% water change twice a week instead of 50% once a week?

you could always dial back the amounts you dose.

but exactly by what amount depends on trial and error and observations of your plants

Yes. The trough and peak will be very close to 50% WC once a week, yet not as stable. You can model the dosing regime here, http://rota.la/ei/. It'll make sense to you after you play around with this.
