Great start! Yes do not add any extra nutrient yet there is enough in the soil.
The biggest mistakes are over watering, too much light and too much nutrients.
Really less is better you can always add later if needed, but your soil got everything for one month at least!
In general only during flowering I add.
Also the strain will determine how big buds will be and how much trichomes too so nothing we can do to boost those if there is no genomics for those already present in the plant!
I wish you a problem free grow!💯👌
