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.
The pH in the growing medium of any plant has a massive effect on the availability of the nutrients in the medium at the plantâs roots. Marijuana thrives best in a slightly acidic growing medium. The reason for this is to do with the natural environments where marijuana first evolved.In fact, with a few exceptions, most plants prefer a slightly acidic pH. The ideal pH for growing marijuana should be considered as a range rather than a specific number.This is because different nutrients become available to the plant at slightly different pH levels. By having your pH sitting within a range rather than at a specific point, you make more nutrients available.he addition of Dolomite Lime to soils at about 1 â 2 tablespoons per gallon of soil is a good way to help control the pH of overly acidic soils. It is worth mentioning that using rainwater for growing marijuana is a controversial subject.
