Typical - there is no typical, it depends on the size of the container, the humidity and temp in the room, the size of the plants, age of the plants - many different variables. It will increase in frequency as the plant gets larger. I started out watering every 4-5 days in 3 gallon containers, and towards the end, one of them needed water every other day.

I always feed with every other watering. Make sure when you water, you water "through" the plant several ounces or so - to help pull any salts from used up nutes out of the soil. You should also test the runoff for PH as well, to give you an idea of whats going on inside the pot
