You will need to water every 55.5 hours with with 2TB of nutes in one gallon of water. But don't water with the whole gallon, only use 97 ounces.
Just kidding, there is no one answer - it will all vary based on your growing conditions and strain grown. If you are using some potting mix from a big box store, it probably has built in fertilizers, in which case you aren't going to feed for a while. You may need to supplement with some iron or calcium, you're going to need to learn what your plants want - read the plant problems forum.
Watering, you don't want to overwater, that's a common mistake. Only water after the top of the soil is dry. You will be able to tell by lifting the pots when it is time to water by the way they feel.
Hope that gives you some pointers, but you probably should read the link Bonzi posted.
Edit - and triclone's link as well. Man I type slow.
