Get yourself either a ph pen or testing drops. WIth that you will need ph up and ph down solutions. Also a ppm meter is good to have. I have a thermometer that has a hand held unit outside my cabinet that displays the temps, humidity time etc. For nutes, you will need a veg and a flowering, I prefer the liquids. There are boosters that you can get to ripen faster near the end of flowering and such too.
Record all your stuff (temps, ppms, ph, size, etc.) in a journal like coil notebook or something. It is a good thing to refer back to for future grows.
Get growing and good luck,
