Unfortunately, when just the leaves turn color, the buds themselves will often look mostly green once they’re trimmed. Bright purple stems may be a sign of a phosphorus deficiency, but this “symptom” is sometimes actually caused by genetics, just like purple leaves, pistils or buds! Blue Dream (rare deep purple phenotype) Blue Dream buds usually don’t turn this deep purple, so if you want to see buds like this you’re better off with a strain that’s bred to always grow dark purple buds. However, the pictures were so beautiful I just had to share! How to Grow Rainbow Colorful Cannabis [REVEALED] Those with minimal knowledge of weed often assume that it is more or less all green.
You may hear about the occasional strain with purple tints, but in general, you might think marijuana looks a bit ‘boring.’ In fact, you can grow cannabis in a variety of colors, as long as the genetics are right. Rainbow Kush , for example, is as brightly colored as the name suggests, while strains such as Black Beauty, Panama-Sedena Red, and Black Russian are all aesthetically pleasing. Alas, you can’t take any strain and turn it into a cornucopia of color. The tendency to produce various colors is almost entirely genetic-based. However, if you purchase the seeds of a colorful strain, you can use a myriad of tricks to bring out the most vibrant colors. Another thing to remember is that there are four different parts of your plant which are capable of producing marvelous colors. Indeed, the buds you hold in your hand are a combination of several hundred calyxes piled on top of one another, and some, or all, of them, can become a color aside from green.
It is the calyxes that provide the most color in your buds. All it takes is a few purple calyxes to provide a purple ‘tint’ for example. When you grind up such weed, you will see the colorful pieces throughout the sample. Obviously, the greater the number of colorful calyxes, the more vibrant the color of the bud. The pistils, or hairs, that stick out of the buds often turn orange, red, purple or pink; even if the buds and leaves stay green. After the buds are dried, they retain some of the pistil colorings, and you’ll also see some of the color looking to get through beneath the buds. In certain strains, the buds stay green while the leaves change color. The result is a stunning plant, but as leaves tend to be trimmed after harvest , you won’t see much of the color on the buds. It is possible for the buds to remain the same while the leaves turn purple, for example. This phenomenon can happen when your plants are exposed to low nighttime temperatures. The leaves exposed to light turn purple while those in the shade don’t change color. Experienced growers often use the ‘trichome’ method to determine when a crop is ready for harvest. Using a magnifying glass, they know that clear trichomes mean the plant isn’t ready. If the trichomes are milky white, the plant is at its highest THC content and prime for harvest . If the color changes to amber or yellow, you must harvest immediately, and the weed will provide a mellow high. In rare cases, trichomes can turn pink or purple, which makes it hard to determine when to harvest. The most important aspect of colorful cannabis is the strain’s genetics. No matter what you do, if a strain isn’t genetically capable of displaying stunning hues, your efforts will be in vain. The genetic ‘building blocks’ are called anthocyanins ; a flavonoid family which produces red, purple, or blue pigments. You also find them in plants such as red cabbage, violets, blueberries, and eggplants. For the record, anthocyanins are a group of over 400 molecules! As we’ll explain a little later, the pH these molecules are exposed to can make a big difference to the colors produced. Luckily, anthocyanins don’t alter the taste or smell of the weed, only the color.
Chlorophyll is responsible for the green color you see in plants. A mature plant begins producing less of this pigment, and at this stage, anthocyanins begin to come through in a variety of colors. As you can guess, some marijuana strains naturally contain greater amounts of anthocyanins than others. This is why certain strains express the same colors time and again. For example, Granddaddy Purple always appears to provide light lavenders and darker purples. Other strains of this ilk include Purple Urkle , Purple Kush , and Mendocino Purps. If you want colorful buds, choose a marijuana strain with colored pistils and buds if you can. In an ideal world, the leaves and trichomes will also be colorful. If you want maximum color after the drying and curing process, deep purple buds are capable of maintaining their colorful appearance once they have been dried and trimmed.
Five Important Factors You Can Control to Bring Out the Best Colors. Strains equipped with the right genetics produce stunning colors under specific conditions. Marijuana produces anthocyanin and flavonoids for protection.
