The 3 or 4 days is just to be safe. Things happen real fast in hydro, you would notice nutrient burn with in a day or 2 in hydro.
I know local growers who run the water pumps 24 hours 7 days a week with out any issues. I would increase the watering cycle slowly, small increase every few days. Then again if it isn't broken don't fix it? Personally i like to follow all the experiments local growers do to see if they can improve the grow.

Good Growing!
