What Causes Pot Plants to Turn Purple

Purple-colored pot plants have a certain beauty and mystique, which is why they are highly sought-after by cannabis fans. Although pot plants can take on many different hues, purple is one of the most intriguing, and often reflects a sign of a high-quality plant. But what causes pot plants to turn purple? In this article, we will explore the factors behind this phenomenon and delve into the science behind it.

Genetics

The purple color found in many pot plants can be traced back to their genetic makeup. Just like physical characteristics that are passed down from parents to their offspring, so too is the color of cannabis plants. Certain strains have a natural tendency to turn purple during their growth cycle, while other strains will remain green. If you want to cultivate purple pot plants, start by selecting a strain that is known to have this genetic makeup.

Temperature

Temperature is another factor that affects the color of pot plants. During the vegetative stage of growth, cooler temperatures can make the leaves of the plant turn purple. When the plant is exposed to temperatures between 50°F to 60°F at night, pigments called anthocyanins develop, which give the leaves their purple color. It is important to note, however, that these cooler temperatures can also slow down the growth of the plant, so it is necessary to strike a balance between growth and coloration.

Light

Lighting also plays a role in the coloration of pot plants. Cannabis plants that are exposed to high-intensity light during the flowering stage are more likely to turn purple. This is because light stress causes the production of anthocyanins, which are responsible for the purple pigmentation of the leaves. In addition, changes in the duration of light exposure during the flowering stage can bring about a change in the pigmentation of the plant.

Nutrients

Finally, nutrients play a role in the coloration of pot plants. Fertilizers that are high in phosphorus and potassium can help to increase the production of anthocyanins, which will lead to purple-colored leaves. However, too much of these nutrients can also result in nutrient burn, which can cause yellowing and brown spots on the leaves. It is essential to use appropriate amounts of nutrients for the best results.

Conclusion

In conclusion, the coloration of pot plants depends on a variety of factors, including genetics, temperature, lighting, and nutrients. If you want to grow purple pot plants, start by selecting strains that have a predisposition to purple coloring. Then, make sure to maintain a stable temperature for your plants during growth and flowering, use appropriate lighting, and feed them with the right balance of nutrients. By following these simple tips, you can grow healthy, vibrant, and uniquely colored pot plants that will impress everyone who sees them.
