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.
That is, a nutrient solution with a Ph of 6.0 is ten times as acidic as a nutrient solution with a Ph of 7.0. A Ph difference of 2.0 is equal to a hundred times increase or decrease in Ph. It is essential to keep the Ph levels within certain limits when growing cannabis. The Ph level of your soil will ascertain how well your cannabis plants are able to take up the nutrients. If the Ph level is out of the correct range, the growth rate of the plants can stall or even stop.
