The Weed Flowering Stages

Do you want to know what to expect when you switch to flowering? In order to maximize your yields, it’s important to know what to focus on during each part of the flowering phase.

It is also very useful to know what to expect in order to know when something is wrong with your cannabis plants! This article is obviously not about Autoflowering seeds.

Week 1-3: Transition to flowering

When growing cannabis indoors, the flowering phase begins when you change your grow lights to a 12/12 light cycle (12 hours light, 12 hours dark each day). Getting those 12 hours of uninterrupted darkness each day gives your plant the signal that it’s time to start flowering. In a way, the plant “thinks” winter is coming because the days are getting shorter.

Outdoors are also the shorter days that cause a cannabis plant to start producing buds in late summer, but flowers outdoors also develop at different times depending on the local climate like in Thailand.

Basically, weed starts the flowering stage when she get less than 15 hours of light. So, if you grow in Thailand, you can start the growth pahse indoor under a lamp for 16 hours to 24 hours a day of light, and put the plants outside when you want them to start their flowering stage.

Week 3 to 4: Formation of the first weed buds

The rapid stretch of the first few weeks will start to slow down in week 3-4, but your cannabis plant will continue to grow upwards. At this point you will start to see real buds instead of just white hairs and all of the pistils will be white.

Mid-flowering stage – week 4-5

From week 4-5, the plants stop growing and begin to grow, enlarging their buds and darkening their pistils.

Week 4 to 5: The Mid Flowering of Weed

Although most pistils will likely still be predominantly white by the end of week 5, the buds are getting bigger and denser every day!

Week 6 to 8: Pistils darken

The pistils are starting to get darker and the buds are stickier and stickier, along with the little leaves around them. Your leaves shouldn’t turn yellow yet at this point, it’s too early

Week 8 to 10: End of flowering, rinsing and harvesting of Weed.

The reward is coming! Patience more than two weeks to last, see a bit less if you are growing fast-flowering cannabis strains. From this moment, it is often recommended to give only water to your plants and to stop the fertilizers of matter to practice a rinsing of the fertilizers and to give more purity to your plant.

The flowers are now covered in trichomes, which are rich glands that secrete THC and other cannabinoids. Now, it’s completely normal for your plant’s leaves to start turning yellow. As long as the yellowing isn’t affecting your buds and you’re very close to harvest, it’s completely normal.

You can’t prevent this happening no matter what you do with fertilizers, because that’s exactly what a cannabis plant naturally does when it finishes the flowering phase.

When the pistils are 2/3 brown, your plant is usually ready!
