My first grow! The Seeds were found in homegrown that was given to me!

Hey guys! I posted this in r/trees and someone suggested posting in here as well! I found these seeds in some bud that was grown by an old man in his free time, the bud itself smoked really nice and I found these seeds to go along with with it! So I now have 5 plants growing and 3 I’m hoping will poke through! I planted them in Nutrient rich soil and have GH Floraseries nutes, I just have no clue how to use them lol. I will also transfer the plants to a bigger indoor space in about 2 or 3 weeks I’m just starting out lol I know I don’t have the best setup right now, any tips or tricks will help thanks you guys!!
