When to use nutrients when you are already using soil with nutrients?

The first time I grow.
And I was wondering if I should start using nutrients when I have a soil that already contains nutrients.
If so, when?
Grateful for help!

i wouldn't add nutes if the soil already has them. you risk nute burn. weight at least 4-6 weeks i would think. i use organic soil without an nutes to avoid the guess work. good luck

Yes wait 4 weeks. There are enough nutrients in the soil already. Gradually introduce them when your plant is ready.
