Phenomenon: Leaves Turning Purple at End of Flowering

Hello, fellow green thumbs! 🌱 Ever noticed your cannabis leaves pulling a Prince and turning purple? Kind of like they’re throwing a late-blooming disco party. 🕺💃 But what’s behind this color-shifting extravaganza? Are they just showing off, or is something more sinister at play? Let’s roll up our sleeves and dig deep into this fascinating…

Phenomenon: Leaves Turning Purple at End of Flowering

What Causes Leaves to Turn Purple?

Notable Purple Weed Strains

Two key players cause this dramatic transformation – cool temperatures and a group of flavonoids called anthocyanins.

Anthocyanins aren’t just a fancy name from a sci-fi movie; they’re naturally occurring compounds in many fruits and veggies like berries and eggplants.

Interestingly, they’re also the secret behind your cannabis leaves turning a royal shade of purple.

Imagine anthocyanins as the cannabis plant’s personal wardrobe consultant, ready to switch up the plant’s green outfit for a purple tux when the temperature drops below 65 degrees Fahrenheit. ❄️🍁

The Role of Anthocyanins

Anthocyanins are the stylists behind many fruits and vegetables’ vibrant red, blue, or black colors.

They’re also responsible for the purple parade in our cannabis leaves.

As antioxidants, they’re like a bodyguard for the plant, protecting it from various nasties like oxidative stress and inflammation.

In the cannabis world, they work the same magic, transforming your average green cannabis plant into a purple showstopper. 🎩

What Causes Leaves to Turn Purple

Now, let’s say a word or two about those celebrities of the cannabis world known for their purple hues.

We’re talking about the likes of Purple Haze (no, not the Jimi Hendrix song, although it’s equally mind-blowing), Granddaddy Purple (GDP), Purple #1, and the ever-so-elegant Mendocino Purps.

These are just a few of the big names on the purple carpet, but a whole world of purple strains is waiting to be explored and admired.

Factors Influencing Leaf Color

Many different factors could convince your cannabis leaves to change their color.

Genetics play a big part – some strains just love going purple.

Temperature is another big influencer.

Cooler temperatures, especially at night, encourage anthocyanin production, leading to that sought-after purple hue.

Nutrient availability is another factor.

For example, a lack of phosphorus during the flowering phase can cause the leaves to turn purple.

But remember folks, nutrients are like hot sauce – a little goes a long way.

Too much can lead to nitrogen excess, causing your plant to turn purple in protest.

Is Purple Color Indicative of Quality?

Is Purple Color Indicative of Quality

Now, the burning question: does a purple plant mean better bud?

While some might argue that anything purple is automatically better (looking at you, Prince fans), the color of the leaves doesn’t necessarily indicate the quality of the cannabis.

It’s what’s inside that counts!

Look for trichome development, and remember to judge the plant’s overall health.

A purple plant might look fancy, but it won’t deliver that top-shelf bud you aim for if it’s unhealthy.

Troubleshooting Purple Leaves

If your cannabis leaves are turning purple and you’re worried (or just don’t dig the color), you can do a few things.

Nutrient Deficiencies and Excesses

Check your nutrient levels.

If your leaves are turning purple, it might be a sign of phosphorus deficiency.

If your plant looks like it’s auditioning for a role in the movie “Purple Rain,” you might be dealing with nitrogen excess.

Remember, balance is vital when it comes to nutrients.

pH Levels and Color Change

Next, check your pH levels.

If your pH is out of whack, it can affect the color of your leaves.

A pH adjustment might be all you need to get your green beauties back on track.

Genetic Factors and Coloration

Finally, remember that some strains are naturally more purple than others, and there’s not much you can do about that – except enjoy the show!

Appreciating the Beauty of Purple Leaves

Let’s not forget to appreciate the beauty and uniqueness of purple leaves.

They add a touch of color and excitement to the growing room.

Plus, who doesn’t love waking up to find that their cannabis plants have decided to throw a surprise purple party?

So, there you have it, folks! The next time you see your cannabis leaves turning purple, you’ll know what’s up.

And remember, whether your leaves are green, purple, or any color in between, the most important thing is that they’re healthy and happy.

After all, happy plants make for happy growers! 🌿🌈


Why are my leaves turning purple during flowering?

That can be due to various factors such as genetics, cooler temperatures, or nutrient imbalances.

At what week of the flower do leaves turn purple?

The timing can vary, but many growers notice the color change around the 5th week of flowering.

Is it normal for plants to show a nitrogen deficiency at the end of the flowering stage?

Yes, this is normal, as the plant uses up stored nutrients. However, a sudden purple coloration might indicate nitrogen excess.

Why are my leaves turning purple during flush?

That is likely due to nutrient deficiency, as flushing removes nutrients from the soil.

What nutrient is lacking when leaves turn purple?

A lack of phosphorus can cause leaves to turn purple.

What deficiency causes purple leaves?
