Week 3 flowering cannabis

For the purposes of this tutorial, the flowering stage starts the day you switch to 12/12

Your plant is going to start getting a little picky about the environment and nutrients in week 3-4 so it’s important to keep a close eye on your garden. You need to make sure your plant stays healthy all the way to the end of the flowering stage, and you’ve still got more than a month to go so you don’t want your plant to run into any major health problems now!
But it’s not normal for your plant to be yellowing or losing leaves rapidly like this

You are basically just maintaining your plant until harvest. Different strains are ready at different times, but from now on you’re going to pretty much treat them all the same. Keep a close eye on the buds, pistils and trichomes as a whole to help you figure out the best time to harvest to get the effects you are looking for.
Spreading out your bud sites and maintaining a flat canopy can increase cannabis yields by as much as 40%…or even more!
During the phase of life known as the vegetative stage (the first stage of life for marijuana), a cannabis plant grows about how you’d expect… like a weed! In the vegetative stage a cannabis plant only grows new stems and leaves, and can grow several inches a day with the added ability to recover from just about anything!
During the first few weeks of the flowering stage, you will see bunches of single leaves forming at the tops of your main colas (like in this pic). Soon white pistils will start coming out of the middle of the bunches, and they will become your main buds!
Harvest buds early if they’re getting damaged!

During the stretch, gently bend new stems down to try to maintain a flat, even canopy

You can maximize marijuana yields by focusing on the right factors each week of the flowering stage. If you know what your cannabis should look like week-by-week, you'll also be able to quickly tell if something is going wrong!

If it hasn’t happened yet, your plants now might develop the known marijuana smell. Make sure to use a carbon-filtered airflow system. Your airflow system is important at this point and fresh air needs to be constantly flowing into your grow room. In this phase, your plants will need a lot of CO2 (carbon dioxide) for growth and health.

Nutrient burn could be a source of declining health of your plant. Make sure not to over-feed your plant with nutrients. You will notice that the tips of the leaves will seem burned if you over-feed your plants.
Remember: Only female plants will produce buds. You can make sure to have female plants by using feminized seeds.

The first 1 to 3 weeks of the flowering stage are a transition phase and your plants will still be growing. Your plants could double their height at this point depending on the type of strain you are using.
When your plants switch from the vegetation to the flowering stage, the growth will eventually get slower. When the plants start to develop flowers (so called buds), it is time to treat them differently. This means changes in light and different nutrients for the flowering stage.
To introduce your plants to this new stage in their life cycle, make sure you are using the right flowering grow lights. Gradually change the light cycles until you reach a 12/12 hours ratio of light and darkness. Again, growing indoor gives you the perfect opportunity to create an environment that suits your plants best. It’s important to take advantage of indoor growing instead of being dependent on the rhythm of the sun. The better your cannabis flowering stages are, the better your yield will be.
In weeks 4 to 6 of your cannabis flowering, the buds will get bigger and fatter. Once the flowers are showing as small white pistils (white wispy hairs), your plants will need more phosphor and potassium. Both are important for a good bud formation. The nutrients support flowering and fruiting.
The entire flowering stage will be about 8 weeks and consists of the following stages: transition, first buds, growth of buds, buds ripen and harvest.

A final, supremely important thing to note about lighting during the flowering stage: once you start switching to the flowering light cycles – never go back. Never expose your plants to light in the dark phase of the day. You do not want to confuse your plants or make them switch back to the vegetation phase. This could dramatically impact your yield. It is the un-interrupted darkness that leads your plants to flower. Make sure this darkness is definite – not one minute of light in the night! Use a programmable timer to make sure you don’t forget when you need to turn your lights on or off, and be sure to test your settings and confirm they’re correct before trusting it on your precious cannabis plants.

These flowering stage tips will take your cannabis production to the next level. It's the moment we've all been waiting for. Weeks in the making, now is the most important part of your plants' lifecycle. It's make-or-break for the success of your crop. Follow these simple steps to ensure you maximize your yields.
