There really isn’t just one best.
You have breeder and strain differences
The your grow medium, soil, hydro, coco?
Do you want to be organic?
But if you like it simple like me and grow in soil. I use fox farms ocean forest soil with 25% more perlite added. Then I use the fox farms trio of nutrients. They give a guide on feeding, but it is recommended that you start at half strength and see how the plant reacts. Then increase as it grows.
I know that isn’t 100% the simplest answer but if your just starting learning it gets you started until you feel real comfortable reading your plants needs.
