hey guys... my plants only need watering once a week, and i was told to nute them every third watering. so thats nutes once every 2 weeks,

is that often enough?

Sort of depends on what kind of soil you're using. If it already contains time-released fert(like Miracle Grow), then every third watering would probably be best. If it's a quality organic mix, then every other watering is fine.

im using peat moss, perlite and vermiculite. no ferts in it.

depends how strong you did it.
I feed every watering but at 1/4 strength, I water first too then add the nutes after I've seen a good runoff of water. I'm using soluble 20-20-20, one level teaspoon to a gallon of water. One cup of solution to a gallon soil.
