Pro mix bx or hp and any nutrients that contain trace elements will do.
Ph balanced, complete 2 part nutes can be expensive but if you like to be lazy then it's worth it to some growers.
I like heavy 16 veg a +b and Prime. No need for flowering nutes. Just use veg a+b and prime until you're ready to taper off.
There are much cheaper ways like Dyna grow nutrients or powdered mixes for cheap. Check out 'mega crop' if that's your style.
I got killer results with Heavy 16 on my GSC and Red Beard pheno run

If you don't want to use external nutrients, there are premade 'super soils' that require only water! They are much more expensive than pro mix, but can be used without adding much or any fertilizer.
If that's your interest, check into some Fox Farm Ocean Forest. It has a lot of food in it, making it ideal for an established plant.
Always start seeds or clones in an insert media because they don't need much and it causes more trouble than it's worth generally.
