While growing a cannabis plant, there are two different stages that it passes through; the pre-flowering stage and the cannabis flowering stage. The flowering phase commences when you notice pistils appearing on the bud sites all over your cannabis plants. These pistils will grow into stunningly beautiful and fragrant flowers that contain the terpenes and cannabinoids that all cannabis consumers adore.
Your cannabis plant’s entire life cycle depends on this growth stage. Mistakes can reduce the number and quality of the harvest, getting perfect yields with exceptional buds.
Continue to read this article ahead to learn about the first signs of the flowering stage as we will walk you through each process, outlining each week by week, and advising you on what to anticipate.
At United Seeds, we ensure that the seeds are handled well after harvesting so that their germination, flowering, and growing stages are taken care of.
When Exactly Do the First Signs of Flowering Stage Start?
Weed plant stages refer to different growing processes, such as seed popping, bud cutting, and curing. Seven phases make up the complete cycle, with the following two being the most important to growers:
- Your cannabis crop grows stems, branches, and foliage during the vegetative stage. It creates the groundwork for tough blossoming.
- During the flowering period, your cannabis plant stops producing green parts and concentrates all its energy on producing buds.
This procedure happens naturally. The plant begins flowering when the days become shorter due to internal mechanisms. In this manner, it generates fresh seeds and maintains its genetic lineage before the chilly winter days.
Since marijuana is a photoperiod plant, the onset of flowering depends on the amount of light the plant receives daily. It occurs at the end of the summer while grown outdoors without overt modification. To achieve this indoor plants, switch the lighting schedule to 10–12 hours of darkness daily.
Symptoms Of Flowering: A Weekly Summary
Pre-flowering, the first phase of your plant’s blossoming stage, occurs throughout the first three weeks. After then, flowers begin to grow, swell, produce a potent scent, and attract your senses. Before buds are fully developing, it will take another seven to nine weeks.
The first week is dominated by rapid vegetative growth. The crop begins to stretch to support the weight of its buds when it believes winter is approaching. During this period, flowering symptoms resemble vegging. Although this growth is the first indication of the first signs of the flowering stage, you shouldn’t instantly switch to blooming nutrition.
Once you enter week 2, how do you recognize a developing weed plant? Each branch’s surrounding greenery twists upward and gathers together. Pre-flower nodes begin to develop at this time between the main stem and fan leaves. From their core, white pistils protrude, signifying the beginning of future smokable blossoms. In week two, budding begins to show itself.
The pre – flowers marijuana had strands growing in the internodes earlier, but now you might see the first indications of actual blooms. In addition, between the leaves and stem are the rounded, hefty forms of the buds, the best moment to completely transition to bloom is this week. Pistils protrude from the green framework, although trichomes and resin glands are hardly present.
By this time, the vegetative stage development has most certainly ended. Trichomes begin to ooze, and the aroma of the completed product is pervasive. Bud sites should be proliferating on Indica specimens, and the onset of the blooming stage in Sativas is delayed. The flowers get bigger and thicker, and they get more white pistils. Bud sites should already be proliferating on Indica specimens.
By the end of week five, indoors and out, we’ve passed the start of the first signs of the flowering stage. The white pistil hairs may occasionally already begin to darken and achieve a mild amber hue. Trichomes, once translucent, have turned opaque, signalling that the yield is about to materialize.
Week 6, 7, 8 & beyond
Since not all strains ripen simultaneously, the final three weeks of flowering are combined. The beginning of the budding cycle also signals that it’s time to flush the weeds. You can observe the buds’ fattening over these final few weeks and complete the necessary pre-harvest tasks. Six weeks into an eight-week flowering period, crops should stop receiving fertilizer. Watering your cannabis plants should be plentiful and clean to wash away extra nutrient deficiencies.
How Can One Determine When An Auto Flower Is In Flower?
Cannabis-grown auto-flowering proceeds in the same manner as its photoperiod counterpart. The only significant variation is speed. After around five weeks after vegging, the first indications of the first signs of the flowering stage appear in auto flowers. Pre-flowering phase lasts one week (instead of two or three), and bud fattening occurs during the following four weeks.
Despite these differences, an auto crop produces trichomes and buds like that of a photoperiod crop. Cannabis grown without grow lights tends to be ready for harvest by the fifth week. That contrasts with photoperiods, which need an additional three weeks to ripen.
Bonus Advice For A Fantastic Crop
It is exciting to see the first signs of the first signs of the flowering stage, but it can be intimidating for newcomers. How do you ensure everything is in order during this critical stage of development? Follow these simple guidelines to ensure that your harvest is always top-notch.
Early Sex Plants
During the first and second weeks of budding, sexing is the simplest. In female cannabis plants, thin, wispy pistils are the first indications of the first signs of the flowering stage. Remove any crops with little balls on the internodes to prevent pollination. Your canna female flowers may develop hermaphroditism under stressful or unfavorable circumstances.
Be Assured Of Healthy Plant Growth
Pre-flowering cannabis that is flourishing portends a robust crop. If you are growing indoors, only change the hours of light schedule when your crops are healthy. With developing plants, shortages and pest damage is far more challenging to fix.
In the big, spacious outdoors, your only determinant is nutrition. To reduce crop stress, gradually go from veg to bloom treatments. Indoor growers can ease the transition even more. Change the lighting, temperatures, and humidity gradually rather than all at once.
Get The Circumstances Right
Speaking of flowering plant conditions, here’s how to keep your burgeoning harvests buzzing with delight:
- Reduce the relative humidity to less than 45% to avoid bud rot
- Keep the daytime temperature at 75°F and the nighttime temperature at 65°F.
- Increase CO2 levels to 1,000–1,200 ppm for bloom.
Change The Lighting
Modern lighting technologies can be used by indoor farmers to produce large harvests. Notably, both the pre-flowering stage and harvest-ready varieties of cannabis enjoy orange and red lighting. Use 580–700 nm wavelengths if at all possible.
Feeding For Flowering
As a general guideline, start adding lots of potassium and phosphorus after the blossoming stage is visible. For precision, use a pre-made fertilizer, and stop feeding if you see any signs of nutrient burn. Both inadequate and excessive feeding can reduce yields.
Remove Extra Foliage
Crops that are beginning to flower should not be trained or trimmed. It reduces the crop’s energy consumption, increases light exposure and aeration, and delivers nutrients to potential bud locations.
Remove all stems and loss of leaves that are damaged. Aim for short, partially formed branches and broad leaves that shade the plant. Cut the leafy areas that are yellow and lifeless while you’re at it.
Strong Branches Support
If you’re growing skinny Sativa strains, flowering plants frequently sag beneath the weight of their buds. By securing bamboo pegs to branches, you can assist them. This support guards against the bending and snapping that can destroy a crop.
Understand Your Harvest Window
Knowing when is harvest time for cannabis is essential for producing potent buds. Combine your cannabis strains estimated flowering time with its aesthetic characteristics. Brown, twisted pistils, and opaque clarity in trichomes are markers of flowering completed. These characteristics ensure that you collect buds with the maximum THC concentration.
Let’s go over what we’ve learned:
- Week one through three is pre-flowering, or the initial symptoms of blossoming. Plants develop quickly and suddenly stop, with pistils emerging.
- In weeks four and five, the pistils darken, buds form, and trichomes cover their surface.
- Weeks six, seven, eight, and beyond aid in the fattening and ripening of buds. Autos are ready to harvest around week five, whereas photoperiods require at least three more weeks.

How to tell when an autoflower is flowering?
When an autoflower begins flowering, its leaves will change from the typical fan–like shape to a more serrated structure. Additionally, the lower branches will start to thicken and be covered in small white hairs that are known as pistils. The pistils are actually female plant flowers forming.
You may also notice a pungent smell coming from the plant which is caused by terpenes being released during this stage of growth. As autoflowering strains progress in their flowering stage, they will begin producing buds that become denser and heavier over time.
Eventually, resin glands form around these developing buds and can be easily spotted with your eyes or under magnification. The trichomes present on the surface of these developing buds should turn milky white when ready for harvest – a sign that your autoflower is finished flowering!
