Using loaded soil for the 1st few weeks u need no nutes
Enzymes/root stim will be beneficial and help wit nutrition uptake
You can add bat guano or some high bloom powders and add ons from some nute maker.
Also there's many other products for taste such as sugars and so on normal soil won't hv 2 provide 2 ur plant.
I'd advise if u want 2 give nutes. Get an organic nutrient line thst takes a few weeks to fully kick in such as Alga line from plagron.
Then there's Xpert Nutrients, great mineral / organic dedicated weed nutes. Silica, master root & enzymes can be given from the jump as they've no ec npk wise they just stims, /zyms. Also then there's resin/taste enhancers such as sticky fingers, sugar shot and their core npk nutes
Good
