The watering depends on how well your soil drains, your local weather conditions, etc, so you have to account for those factors. I set my drip system for one hour every three days, which provides roughly a couple of gallons of water for each crown. If we get a run of wet weather I shut the drip system down until the weather turns dry again.
I don't do a lot of "fertilizing", instead rely on the bedding to provide most of the nutrients for the hops. Lots of horse poop mixed with loam and adjusted with some sand or vermiculite to maintain good drainage will go a long way. When I do feel the urge to fertilize I just use Miracle-Gro.
Last year when the growing season ended and the bines were cut down I dug down about a foot around the edges of the beds and mixed in more bedding material. There was enough good stuff in the beds that I didn't apply any fertilizer until mid-June because all of the plants had grown tall and thick on their own...
Cheers!
