For some strains, the leaves may turn purple while the buds stay green. The leaves of this plant turned purple overnight after that plant was exposed to chilly night temperatures. The leaves exposed to direct light are most likely to turn purple, while leaves in the shade often stay green.
In this case, all the leaves that are exposed to the light have turned purple, including the sugar leaves. However, once the leaves are trimmed off, the buds will be mostly green. Buds may still be purple-tinted from leaves that weren’t completely trimmed off. If there’s a lot of purple leaves, there may be a lot of color left even after trimming. The top leaves of this Super Purple Haze plant have turned a vibrant purple. Here are the buds from that Super Purple Haze plant drying – you can see that the parts of the buds that were exposed to the light have strong hints of purple.
A closer look at those buds so you can better see how much bud is purple and how much is green after being trimmed and dried (click for a closeup!) This cannabis plant has grown vibrant red and purple leaves. This outdoor cannabis plant has turned purple everywhere it received direct sunlight. Cannabis sometimes has neat mutations, like this two-tone plant where only half the leaves turned purple! These Swiss Cheese plants by Nirvana exploded with red, pink and purple leaves when it got cool at night right near harvest time, but the buds themselves did not change color. 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.
