How long is a piece of string?
Without knowing which growing technique you are referring to, answers with any accuracy are incredibly hard to give.
Soil? Hydro? Coir? DWC? Indoor? Outdoor? They all have different needs, hence the string comment.
Then plant size, strain, temps and the plants actual requirements, will all cause different water and feeding schedules.
Growing outdoors in soil that I blended myself, I may not need to feed for 6+ weeks and might need to water twice a week or twice a day, depending on plant size and summer temperatures. There are really no hard and fast rules when it comes to watering and feeding, unless you are growing hydroponically or in a DWC system, whereby the plants have a constant source of water and nutrients.
Remember too, under watering or under feeding is very simple to correct. Over feeding and having to rescue burnt plants is incredibly difficult to remedy.
Hope this (vaguely) helps,.....
