If i were you, I would get some Schultz all purpose plant food (10-15-10). This can be found at a lot of places. Wait until the 2nd or 3rd week until feeding your plants; ALSO, make sure you start off with either half or quarter of the recommended amount, until you figure out what your plant can handle.

As a user of cheap nutes, I currently used Miracid for veg (30-10-10). Other growers don't like Miracle Grow products - but frankly, this is an effective nute for beginners that don't have Hydro shops to sell FF and other sorts.

I'd say w/e is easier to find, use that nute for veg

When you begin flowering, you'll need a different nutrient, but don't worry about that immediately. Try to focus on lighting and veg nutrients for now.
