tataceanswered grow question 2 years ago Hi, plants in nature only need the essential nutrients they find in the soil, a good complete N-P-K line + microelements is enough, the only really useful supplements are silica (But if you grow in the ground, you don't need it because already present in the ground) and any stimulating hormones (If you want to try your hand, use only natural and safe things, some hormones are carcinogenic and are absolutely not something you want just for 20g more). Good luck friend!
