I don't think petite is a height so much as a body shape. I have seen tall women shopping in the petite section because they have a short waist or shorter arms or wanted a skirt that fits them better than the regular ones, and I have seen smaller women shopping in the junior/misses/womens section for similar reasons.
Sweet clover needs a high pH, 6.0 or higher, for proper nodulation to occur, and it has a higher calcium requirement as well. Sweet clover is able to obtain phosphorus from relatively unavailable soil phosphates and will grow on soils where alfalfa, red clover or ladino will fail.
In hydroponic solutions marijuana grows with a low pH of 5.5. Marijuana grows best in water or soil with a pH level between 6.0-6.5 (slightly acidic). Good garden soils consist of this pH level. In this range the plants nutrients are water soluble. This means that the nutrients are available to the marijuana plants. When the pH level is outside of this range, the nutrients become less available because the nutrients wonât dissolve as well. There is only one accurate way to adjust the pH.
