Naturally occurring forms of vitamin K include a number of vitamers known as vitamin K 1 and vitamin K 2 (Figure 1). Vitamin K 1 or phylloquinone is synthesized by plants and is the predominant form in the diet. Vitamin K 2 includes a range of vitamin K forms collectively referred to as menaquinones. Most menaquinones are synthesized by human intestinal microbiota and found in fermented foods and in animal products.
Hereâs what it likes: 1  A lot of nitrogen in vegetative phase. 2  Less nitrogen, more phosphorus during flowering phase. 3  A PH range between 5.8 and 6.3. About 6 is the best.  A balanced ratio of soil fungus to bacteria. Because marijuana prefers slightly acidic soil, it may be a little on the fungal side.

This is why indoor growing requires a different technique that will compensate for this lack of space. To put it simply, the root systems of indoor marijuana plants need to be smaller.
