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.
Make marijuana soil yourself. Soil is pretty easy to mix, as long as you pay attention to the ratios. These ratios also will change according to which stage of life your marijuana plants are in. Early stages of life, for instance, require balanced amounts of turf, perlite, and worm meal.
