Bro first off welcome to the forums! AFN is fucking tits man, so much help and great vibes all around.
I just started 3 Fast & Vast myself. Hopefully they will be above ground today ready to face the world! Check out the link in my sig so that you can watch this strain as I grow it so you will kind of know what to look for and what to expect. My thread will also let you know what soil and nutes I am using this grow.
On the nutes there are so many different ones to choose from.
For a basic concept of nutes, you divide your grow cycle into 2 separate ones: Vegetative (aka grow) and Flowering (aka bloom).
You will want to look into nutes that serve the 2 main cycles. Veg nutes will be fed while your plants are getting big and vegging, while bloom nutes will be used once they start to flower or bloom. This separation will help provide the correct type of nutrients that the plant needs at different times in it's life. There are many many options to chose from, but many brands offer full lineups. Meaning they provide the 2 basic cycle nutes veg and bloom, and many companies also offer additional nutes that help bridge the gaps (which for your first grow I would reccomend not getting to carried away - Keep it simple!).
The crazy thing about nutes is that they highly depend on on your plant and your soil, so some people may use 6-7 nute products while others may only use 2 or 3. There are so many combinations that work for growing, so grab some munchies, light up a doobie, search the forum, start reading, and DIG IN.
