I would use the same feeding schedule as any other hydro.
Do you mean nute, flush, nute, flush during grow n flower? If so its not required, just flush at the end.
I would use 1/2 to 3/4 the ppm for aero than what i would use for hydro because your system will get less clogs and with aero your plants absorb more nutes so no harm in a lil less nutes.
