i would need more info to say for sure..but to wing it, if your in veg, with 18 hrs of light, a good schedule for soil is flood the table 6 times or so, give or take a feeding. flood the table so the water is at the top of the pots(cloth pots work verry well with this system) and than stop pumping, and drain. as for the 6 hours of darkness, feed once or twice. if your in flower, flood the table 3 or 4 times in the light, and same in the dark. however if you are doing hydro, youll probably want to flood the table a few more times in each setting. seriously though, cloth pots area blessing in this system.
