Some deficiencies may come to be useful as they don’t actually kill the plant. Nitrogen deficiency in cannabis plants leads to a decrease in chlorophyll, which consequently turns the cannabis leaves yellow. Lack of phosphorous will give your cannabis darker green with purple veins or even slightly red buds. Yet, this strategy is not recommended as it’s not as healthy nor will it yield as satisfying results.
Much like autumn leaves, cannabis will express different colours when exposed to shorter light and temperature cycles. This will mimic the change of season, which a grower can easily replicate in an indoor grow room.
Judging a book by its cover is what humans do. Over thousands of years, we’ve developed into creatures that need to make decisions fast. Ever since the stone age, we’ve judged individuals, foodstuffs and housing by appearance. It’s no surprise that nowadays, we judge cannabis in the same way.
The main concept to grasp here is the word “anthocyanins.” These are a group of over 400 pigment molecules present in many fruits, vegetables and flowers. They can manifest in different colours depending on the pH they’re exposed to. These molecules do not alter the taste or the smell of the plant. It’s your everyday ganja, besides the colour.
It has always been a mystery to most people how cannabis comes in different colours. Does it taste better? Is it more potent? Too many questions were unanswered, so here is our guide to all things colourful cannabis.
There are several methods that growers use to alter the colour of a cannabis plant. Some changes affect the whole plant, while others affect only the buds. Some start showing tones from an early stage, while others only come to light near harvest.
In some rare situations, strains develop genetics so dark that they appear black. These strains are most common in Vietnamese landraces. These are genetically pure strains, the ones not altered by years of selective breeding by humans. They’ve naturally evolved into strong and even psychedelic strains. Black cannabis is noted for giving strong cerebral highs with occasional visuals. But this has nothing to do with the colour.
This colorful weed produces an attractive black color. The buds are filled with calyxes; the plant will thrive, loaded with buds in large sizes. The Black Diesel will need around nine to ten weeks flowering time, and by the end, it will generate the pleasant smell of Grapefruit. They are best grown outdoors; the strain will expect a harvest on the verge of October. It has no special attention needed, just a favorable climate, preferably warm.
Originated from the West Coast, this renowned strain of cannabis is a fascinating colorful weed that thrives and develops extremely fast. This weed is highly resinous and comprised of an insanely high THC level. They start to show black color when it reaches the end of the flowering period.
This list of colorful weeds is not authentic and complete without the presence of Rainbow Kush. The offspring has bold colors with entire colors visibly identified from the crossbreeding of Blueberry and Dancehall strains. Apart from its colorful appearance, it provides tropical tones of taste and smell. It has a stunning high that radiates euphoria.

The variety of available weeds in the market mostly differ in taste, potency, quality, and effects. However, the appearance of weed will never fail to impress the connoisseurs.
Some strains grow vibrantly and colorful as compared to the usual green and subtle red and yellow hues. Due to the promising and attractive appearance, these types of colorful weed are falsely characterized as more potent than others with less color.
All types of green plants are comprised of carotenoids, yet these are coated with chlorophyll; hence, they are not visible until the plant reaches the last stage of growth, and chlorophyll is lessened in production.
Growing this type of weed requires standard provisions of requirements and nutrients. However, dropping the temperature during the night is the best way to emphasize its back hue.
For this Purple Trainwreck cola, it’s mostly just the leaves turning purple. In either case, the effects are the same!
Note: Some strains turn color no matter what the temperature. You can sometimes contact the breeder and ask if they have advice on how to bring out colors for a particular strain. I’ve found that most breeders will get back to you quickly if you go to their website and ask questions!
This Auto Frisian Dew plant got a little stunted at first, but still ended up producing beautiful purple buds!
Although color is determined primarily by genetics, there are a few things you can do to help your plant express its natural colors…
When people are talking about “colorful” buds, most people imagine brightly colored buds in their hands. But there are actually different parts of cannabis plants that can display non-green colors, and sometimes people will lump all them all together. Each one is a little different from each other, and some have a significant effect on the final looks of your bud, while others don’t make much difference.
Purple or pink trichomes can make it tough to know when to harvest, but they’re exotic and beautiful! The color of trichomes may leave a slight tint on the buds after they’ve been dried and cured, but the bud color underneath will be the dominant color.
For example, the flowers of specific types of hydrangeas can turn blue in very acidic soil but may turn pink if exposed to neutral or only slightly acidic soil (though this type of variation is rare in the plant world).
