Typical Questions about growing

I know I can probably find this on the search but I am in a hurry and will be going to the store in less than an hour.

Things I need to know-

What N-P-K is best for fert?(I just want to stay with one fert not one for every cycle)

What Nutes are essential?

Are HPS that big of a difference when growing(I am growing in a small area, so small plant, about a meter high)

I have Ph tester, and Ph up.

Are there websites that ship worldwide(or to Europe) for cheap lighting, nutrition, etc.?

I want to keep my plants small, dense, and more horizontal.

Thanks for your help guys, you rock

NPK- you can't complete an entire cannabis crop on a single fert. The grow shop guy willl help you on that. You need a veg and a bloom.
Nutes- the ones that come in the grow and bloom bottles
HPS- YES. But for a small area, get a small HPS.
Yes
Good luck
