One trick to do is use nutrient-infused soil to avoid giving other nutrients that may be too much for the plants. Since this part is very crucial, there is a need for extra care and attention. Make sure it gets the right amount of water, sunlight, and good airflow.
After three weeks, more leaves will appear. During this time, pre-flowers will appear, and it will be easier to know the gender of the plant. Once these pre-flowers start to grow, knowing how to tell when autoflower is flowering is now easy to know. The grower who uses feminized seeds will have nothing to do but to let the plant grow and mature, while those using regular seeds, it is important to know which plants are male and female. Unless the grower is trying to get seeds from an autoflowering plant, the male plants should be separated from the female ones.
How to tell when autoflower is flowering – Pre-flowering and Flowering Stage
Perhaps the most-awaited and exciting part of planting marijuana plants is witnessing the process of how the plants grow and mature until harvest. For pro growers, this might be a typical and mundane incident, but for a beginner grower, this is where the fun starts to reveal. The traditional marijuana plant strain like Indica or Sativa goes a long way before it matures, but the autoflower strains offer a different process since they mature and grow in a shorter time. To get to the harvest time correctly, it is essential to know how to tell when the autoflower is flowering.
Pre-flowers of a female plant look like a small bud with white hairs. The white hair is a pistil, and this will get in contact with the pollen from a male plant in order to germinate seeds. The pre-flowering stage is easy to identify. In this stage, a lot of leaves are already growing. The plant is in full force in growing fast, so the nutrients must be enough. The pre-flowering part is usually called the vegetative stage, where the growth of the marijuana plant is very crucial. The vegetative stage will decide the quality of yield the growers will get.
Before a grower knows how to tell when an autoflower is flowering, one must be an expert in knowing the basic life stages and marijuana plant proper care and attention. With those things combined, the grower will have an easy way to tell when autoflower is flowering. It might be a little discouraging when failing the first time, but even pro growers started at the bottom without knowing all the basics. So, the beginner grower must be open to multiple mistakes and strive to learn more through researching and seeking help if possible.
As you may know by now, after 3-5 weeks your autoflower should be transitioning to the flowering stage but if the weeks go by and you don’t see any signs of stigmas (white hairs) there are a couple of things that could be causing this.
No matter what time of the year outside you decide to grow your autos, after the fourth week of growth the plants will begin to transition into the pre-flowering stage. This means they will shift in auxin production and focus on flowering causing a hormonal change and a preference for certain nutrients. When your plants start flowering you have to make sure that you’re providing higher doses of phosphorus and potassium, these are the main minerals your cannabis plants need to produce buds.
How To Recognize Pre-Flowers?
The name of the white hair is stigma and will emerge from the calyxes. As the female sex organ, it is the stigma that must come into direct contact with the pollen in order to produce seeds.
When your plants have completely matured and the stigmas have turned brown, your plant won’t take more than just a couple of days to be completely mature, at this stage you’re just waiting on the state of the trichomes to harvest your buds at the right time.
Remember that you don’t need to follow this table but it may be of help, by knowing exactly what effect each state of the trichomes provide you can fine-tune your harvest when your plants will provide the desired effect, so for example, you don’t want a super-strong head rush, you can harvest when 50/50 of the trichomes are amber and cloudy, resulting ina more balanced effect.
2: its not flowering but has pre- flowers . then its flowering .
1: its an auto . why distinguish between veg and the other one?
3: veg and ‘bloom’ are photo periodic terms used by ‘sewage bottlers’
and other carpet baggers to entice you to spend more,
as you will find less is best with all autos
I would run a 50/50 veg/bloom mix until it shows solidly in bloom. Basically just give it access to increased P and K with a bit reduced N. Then you can go solid bloom once the plant really gets into flower. It like most other plants will still use more N at the beginning of it’s life and more P and K at the end. I don’t see a need for a sudden transition, I just start adding more bloom and less veg as it proceeds into flower. This is assuming you are in something other than soil.
I just harvested 2 vision northern lights autos. They weren’t the fastest autos. Flowering didn’t start until at least weak 6, took about 11 weeks total.
