with a new bag I would do a 1/2 cup with the amendments you have , just make sure the ph is in the boundary’s PH is very important cause the ppms could go as high as 2000 … with being under LEDs they need that food , but you want to work the plant down to 600 ppms so your not feeding as much , but giving there herc and tea , one way to save a few $$$ and still put out great product …. Why is it so good? Growing organic and no pesticides on product , a lot are just rushing it , it’s all about weight and not the flavor …
