Buds will not have grown too much at this point, so don’t worry if they are still fairly small.
The rest of the growth is up to the plant, but when it seems to be getting close to harvest time flushing nutrients is important for quality tasting harvest. Simply flush the plants with pH-balanced water and stop administering nutrients at this time to ensure a good harvest.
There will be a ton of foliage at this point and the plants will want more water than seems possible. Any training should be done at this stage, as long as the plant is healthy and growing rapidly.

The length of the vegetative stage of growth is dependent on the genetics of the plant, as well as the period of time they are receiving light. Plants can technically remain in the vegetative state pretty much indefinitely, but eventually, they will hit their max growth or the amount of growth comfortable for the room and need to be switched over to flowering.

It will grow a bit taller and begin to straighten up during this week. The very first new growths will appear as well, which will be another leaf along with the development of additional blades on the current leaves. Initially, they will be quite small.
It can last anywhere from 3-16 weeks, so knowledge of the particular strain being used is crucial here.
Today I would like to feature the following incredible marijuana growing time-lapse photography and videos, many of which were produced by fuzzygrow. View all of her time-lapse videos here: http://vimeo.com/user15676933/videos
Watch as these young plants are trained to fill up a ScrOG net. ScrOG stands for “Screen Of Green” and refers to using a “screen” (usually made of string) to force plants to grow into a flat canopy.
New Life – The birth of a marijuana plant from seed
The cotyledon leaves unfurl and start gaining height above the soil. You can see the first “true” (wrinkled) set of marijuana leaves nestled in between the cotyledons at first, and as time goes on these spread out to catch as much light as possible.
I sprayed Dr. Doom on this young plant to try to combat spider mites. Plant is under a 42w CFL. The main apex was also burned which stopped growing but eventually a new one formed off center. New leaves sprouted just above the cotyledons as well. Don’t spray pyrethrum-based products with any grow lights still on! Pyrethrum is an ingredient in certain insecticides. In this case it came from Dr. Doom. Pyrethrum is very photoreactive so because it was sprayed with the lights on it created a bad situation on the plant as you can see. It almost appears to burn it. The growth was very gnarly for awhile afterwards!
While we don’t fully understand the mechanism behind this movement, some scientists speculate that it was developed as a way for the plant to “explore” and find the best direction to grow, since even though plants are rooted, the difference of even a couple of inches can make a huge difference in the survival of the plants.
Nicknamed “diet weed” by those who use it, Delta-8 THC looks and smells like the real thing, except without side effects like paranoia. Here's why it has experts concerned.

Marijuana sales soared in 2020, from $10 billion the year before to nearly $18 billion. Experts say the pandemic played a major role. "I think people turned to cannabis to help relieve stress," says author of Weed the People Bruce Barcott.
A new study from researchers in Canada has found a higher likelihood of autism in babies born to mothers who used marijuana. Experts weigh in on what we know thus far.
The Indiana State Police issued the warning on Facebook earlier this week, alongside photos of “medicated” Skittles and Starburst Gummies, which contain THC, the psychoactive compound of cannabis.
