Anyone know what nutrients NPK dose??

it is weird i find the fertilizers with 5-15-5 and different settings but how do you know which one you need??? i will be planting in soil and i have no clue which nutrients to buy and suggestions???

Buy whichever kind you want.

as far as recommended nutes, for a newbie, follow the tips for a tomato plant in veg. you want high N (20+) in veg but do NOT buy time release soil if u can avoid it. FoxFarm is expensive but its the ultimate recommended soil and nutes, there is more info on the site. Search around here and feel free to ask more if u have questions
