Consensus on what? Growing a plant? There are centuries of knowledge on the subject. There are scientific studies done on plant growth. Today's cannabis broscience is a joke. I don't do anything cannabis specific. I treat cannabis like the plant it is and it grows and flourishes. I use the same nutrients in my garden, for my flowers, and houseplants. The only thing I do differently with cannabis is control the light hours. 12/12 for flowering. Other than that I do the same thing I do with tomatoes, peppers, cucumbers, dahlia's, lilies, etc... The people stuck on cannabis is special and needs all these cannabis specific products are people that have never grown anything in their life. In fact cannabis is a very easy plant to grow and many people would struggle trying to grow a tomato or pepper plant.
