Color refers to the different and various shades of cannabis. Depending on the type of crop you are growing and the temperatures and overall climate the cannabis is growing at, this can have a huge impact on its color. The color will also depend on what stage or cycle of growth the plant is currently at. Sometimes it can look like a shade of purple in one cycle when the previous week it looked more like a shade of green. the genetics of each strain plays a huge part in the color of the plants.
Some of the blueberry cannabis strains will look blue and Purple Haze will appear purple, and many cannabis strain names are named that way due to their color. Anthocyanin is a pigment that plants generate as a result of their genes, deficiency in potassium, and temperatures getting cold. The color of a plant may sometimes lead the grower to think that it is doing well when it might actually need nutrients or fertilizer.
The plants that have an alteration in their color due to their genes will typically change color in the buds, trunk, and stems. If the color is a result of their genes, it’s not possible to change this. If their genes are not to blame for a change in color, a lack of phosphorus could be the answer. This will in most cases, be revealed during the flowering phase.
If the plant is a healthy green color in the growth cycle, and then turning purple or red in the flowering cycle, phosphorus is usually to blame. 10 degrees Celcius is usually the temperature that cannabis plants will start to change a darker blue or purple color. Indica strains are known to be a little tougher than sativa strains and are said to be able to withstand colder temperatures.
