Light intensity
To some degree, more light translates to fatter buds and higher yields (you'll need to pay attention to the distance between your grow light and plants or your plant may suffer from light burn). Increasing light intensity is the most effective way to fatten up buds.
Phosphorus technically helps the plant move energy from one part to another, which means that it helps the plant produce bigger seeds, stronger roots, and bigger buds. Potassium makes the plant hardier and stronger, better able to withstand hardship or disease.
General Hydroponic KoolBloom
Available as Liquid KoolBloom or Dry KoolBloom, this additive is widely regarded as the best bud hardener out there.
Instead, utilize organic fertilizers like worm castings, blood meal, fish meal, or bat guano for nitrogen; bone meal or rock dust for phosphorus; wood ash or kelp meal for potassium; and dolomite lime for calcium or magnesium.
Lack of light is perhaps the most common reason that cannabis produces fluffy, light buds. You may have noticed the lower, puny 'popcorn' bud sites that form below the main canopy.
Any kind of stress, be it from poor watering, a lack or excess of nutrients, the environment, pests, plagues, or improper care, can affect a plant's ability to grow big, dense flowers.
Because bud formation starts after 7 hours of dark period, it is also wise to always maintain a minimum day length of 17 to 18 hours during the vegetative period. A dark period of 12 hours is used as a standard in cannabis to ensure a smooth flowering process.

Weeks 4-6: Buds Fatten Up
They'll still have all the white pistils sticking out, but you'll be able to see the buds getting bigger every day. At this point the “stretch” is about over and you can reduce the amount of training you're doing with your plants.
Fill your reservoir with fresh water and add your base nutrient and any other additives. Add Big Bud to your nutrient solution at a rate of 2ml per litre and stir well. If you have used only Advanced Nutrients products in the 'pH Perfect' range, there will be no need for pH adjustment.

What Are the Most Common Synthetic Hormones to Create PGR Weed? The three most common synthetic PGRs used in cannabis growing are chlormequat chloride, daminozide (a.k.a. Alar), and Paclobutrazol. All three inhibit growth, ensuring the flower becomes the largest and densest part of the plant.
Cannabis needs more nitrogen (N) when vegging and more phosphorus and potassium (P & K) while flowering. If you give then too much nitrogen during bloom, it'll slow down bud growth and result in lower yields of fluffier buds. That's the exact opposite of what you want!
Poor Airflow
Buds seem to fatten the best when they get plenty of light and fresh air. You've already taken care of light, but you should also ensure your plants get excellent airflow. Air circulation helps control humidity, prevent wet spots, and moves air through the plant and around the buds.
Because bud formation starts after 7 hours of dark period, it is also wise to always maintain a minimum day length of 17 to 18 hours during the vegetative period. A dark period of 12 hours is used as a standard in cannabis to ensure a smooth flowering process.
During week 2, the first white pistils will grow on the female cannabis plants. These fine, wispy white hairs develop at the locations where the big fan leaves meet the main stem. These white hairs are what later become the buds of the plant, called colas.
Late flowering / Ripening stage – week 6 to harvest
In the last few weeks, buds gain the most weight. They are sticky to the touch and can be very smelly.
The flowering stage is when your plants will produce buds and what we commonly refer to as “weed”. During the flowering stage, your plants should be ready to harvest after 8-12 weeks, depending on the strain.
Uninterrupted Darkness
The moon and stars don't bother cannabis, but any artificial light can stop its bud growth. In fact, light interrupting its dark cycles can make cannabis so stressed and irritable that it can lead to hermaphroditism. That can pollinate females and ruin your plants.
The Final 2 Weeks Of Flowering. If you grow strains with an average flowering time, the majority of bud development will occur by the 6th week of bloom. In the last two weeks, the buds will mostly be ripening and not really growing much more in size.
Environmental Factors are Important for the Cannabis Plant
Another reason that a cannabis plant may have small buds is due to environmental factors. If the plant is not getting enough light, it will stretch out in search of more. This can lead to a large plant, but small buds that are spread out along the stem.
