Nearly all cannabis seedlings, no matter how the seeds are sprouted, will start with just two leaves per set, like the following:
Normal cannabis seedling (2 leaves per set)
Every once in a while, growers will run into a “trileaf” seedling. This is a relatively common mutation, and you’re likely to run into it if you germinate a lot of cannabis seeds. 3-leaf cannabis seedlings should generally be treated like any other seedling.
They will grow about 1/3 more side branches than regular seedlings, so a 3-leaf seedling might be a good candidate for cannabis plant training or a ScrOG setup.

2.) Two-Toned Leaves
Two-toned leaves usually have split coloring in a relatively straight line. This mutation often affects just one or two leaves on the whole plant, though sometimes you’ll get a whole stem or part of the plant that displays this characteristic.
The two-toned leaves don’t seem to have much effect on anything, but it’s kinda cool looking!
I believe this happens due to a type of “variegation” (wikipedia link) and may be due to “sectorial chimera”. Other plants besides cannabis plants can have this happen, too!
Not to be confused with a nutrient deficiency, this mutation usually affects just one or two leaves on the plant. Nothing to worry about! Sometimes half of the leaf will turn purple….
More commonly, half of the leaf will turn light yellow or even white.
3.) Buds Growing From Center of Leaf
Here’s a normal cannabis leaf. Unfortunately, as beautiful as these leaves are, they normally contain no THC.

Cannabis leaves that are growing buds
(these cannabis plants have THC-encrusted buds growing from center of leaves)
This is a mutation I’d love to see on my plants one day 🙂 Though strangely placed, these buds are like any other buds found on the plant. You just get a couple extra buds encrusted with THC & trichomes!
The following leaf-bud has grown a single calyx with a few pistils
Here’s another amazing plant – imagine what you could do with all the trim!
The following nug is almost 1/2 gram – Talk about a bonus!
4.) THC-Filled Trichomes Can Grow Just About Anywhere on a Budding Cannabis Plant
Growers are breeding strains that produce more and more trichomes all over the plant.
Trichomes are small, glandular stalked resin glands that carry the majority of cannabinoids and THC produced by the cannabis plant.
A bud covered in trichomes will have an almost “sparkly” or “glittery” appearance. Cannabis breeders are selecting cannabis plants which produce more of these sparkly trichomes not just on buds, but on leaves and stems close to buds This is done with the purpose of getting more potency with the same amount of time, effort and space.

5.) Some Buds Make “Fox Tails”
Bud with little foxtailing – common with Indica-based strains (buds are rounded out, sometimes one foxtail visable near top)
Massive foxtailing can be a genetic trait, and certain strains will tend to produce foxtails all over their buds no matter what. This seems to happen most commonly with Haze and Sativa-based strains.
This way that buds can grow is named after “fox tails” because the buds tend to grow in a rounded shape with the fluffy hair-like pistils coming from the end.
Example of healthy foxtailing based on genetics (notice how there are fox tails all over the bud, instead of just at the top)
However, massive foxtailing is often the result of heat or stress. You know that’s likely the case when the foxtailing seems to be happening most in the parts of the plant that are close to a heat or light source.
When a single foxtail keeps growing longer and longer, it is almost always a sign of some sort of major stress to the buds, most often heat.
This massively long foxtail was caused by heat (it’s basically a very long and thin bud, and will likely never fill out)
Here’s another foxtail that was triggered by too much heat
The following bud erupted with foxtails after a heatwave (the plant also suffered from nutrient stress, which can trigger foxtailing on its own)
6.) This Is What Cannabis Roots Look Like
This incredible roots picture was taken by grower Ramon. The plant was first grown in hydro (with the roots grown directly in water), then transferred to soil.
7.) Cannabis Seeds Can Carry “Twins”
Twin tap roots can sometimes emerge from one cannabis seed. This is sort of like your seed having twins, because each new root has the potential to form into a separate plant.
“I had one of those on my first grow. Plant it, and once it sprouts up, you can GENTLY and CAREFULLY seperate the 2 plants and transplant one to a new pot. If you leave them both together, the stronger one will “starve” the weaker one, so to speak. When I split mine apart, they both grew nice and big :D”
From the grower, “When I got the seed it looked really deformed.”
“[Twin seeds are] fairly common. I’ve had some seedbatches that had ’round 30% ‘twins’. However, what I haven’t seen yet* is a set of twins that come out one male and one female. It’s odd, because the twins usually differ in various traits, they’re not really clones of each other. If one were to get a M/F pair of twins, an apomictic (wiki apomixis) cross could be made between the two, which would (in theory) produce a strain with stable traits in just one generation. “
*yet has been 46 years so far….
8.) Vegetating Cannabis Plants Have an Amazing Ability to Heal
“This is a white widow a couple of weeks into flower, quite nice, but look to the bottom of the stem and you see a big ‘knuckle’.”
“This lady was snapped mid veg by accident. She was completely on her side and connected to the main stem by a few fibers and a sliver of ‘skin’. The ‘connected’ tissue was around 1mm, (around the thickness of a credit card).
“She was roughly taped upright with some very haphazard wrapping with electrical tape and forgotten about. Not only is she looking pretty good, (for a small pot and relatively modest light), she’s not at all delayed or less healthy than her sisters. I guess the message is never give up…”
9.) It’s Possible to Bleach Plants With Too-Bright Light
Light Bleaching – most common with high-power LEDs, but can also happen poorly ventilated HPS lights that are kept too close to the tops of the plants. Basically, this is what happens when plants get too much light, kinda like how hair on top of your head can turn lighter if you spend a lot of time in the sun.
Buds which have been bleached tend to be low potency or even have no potency (no available THC or other cannabinoids). Therefore you should avoid light-bleaching your plants at all costs!
Sometimes light-bleached cannabis will get mis-labeled as “albino cannabis” or “white cannabis” but the truth is that the white color is not healthy, so this is not a desirable trait (even if it looks pretty cool).
10.) Flowering Cannabis Plants Can Make “Sap”
Sap – there’s lots of speculation about what it is. No one knows for sure. Many growers who have run into this agree that the type of sap produced is sweet and doesn’t contain much (if any) THC. It is mostly made of sugar and water and so is not smokable. Seems to be related to the plant over-producing sugars, and sap productions is more common when
Using sugar supplements like molasses, Botanicare Sweet, Sugar Daddy, etc.
Big temperature difference between night and day, especially if it gets cold at night
Certain strains or individual plants seem more likely to produce sap
“Strain: Kosher Kush. Flowered her for 70 days and she was covered in trichs. When we harvested her we noticed about a dozen of these sap like globes. They range in color from clear to amber.”
“The plants had already been flushed properly – I let the soil dry completely and fed the plants 2TBSP/gallon of molasses, let them eat and then flushed them out again and waited 2-3 days before harvest. Both plants started producing excretions all over. I’ve seen this before, sap leaking from the stem of plants, however personally I’ve never seen it on the buds themselves. What I believe happened is the pores of the plants either get clogged and therefore “pop” for lack of a better word. Or, the plant liked the molasses better than it’s natural sugars and forced some of those out. Either way I’m going to try this on another plant and see what happens. Is there a benefit to it? Probably not, but I’m going to get the substance tested. I’ve ingested all of the little sap pockets I’ve found and while it tastes like canna, it doesn’t seem physchoactive. Who knows, it could be loaded with CBD or something else.”
Stem Sap (more common) – often appears to seep out of injured parts of the stem, but not always! Sometimes sap seems to ooze out of uninjured parts of the stem.
What’s interesting about this case is that the plant naturally did something that the grower would normally have to do themselves. Cannabis plants normally grow in a triangle tree shape, and growers often must cut or train the plant in order to grow more low and bushy.
Growers sometimes accomplish a low and bushy growth pattern with a plant training technique known as “topping.” Learn more about topping
Here’s two normal young cannabis plants, each with a regular growth tip (set of leaves) at the top:
Normal cannabis plants
So to get rid of this top growth node, a grower would normally cut it off, like this
Now the following plant had a strange mutation…
This plant randomly grew a leaf instead of a growth node, so it naturally topped itself, take a look!
BlackJack – get the effects of a Sativa or Haze with a plant that is actually suited to indoor growth, short and easy to train. BlackJack produces a potent soaring effect that hits hard, fast and is long-lasting – unbelievable number of trichomes on the buds and leaves. Suitable for medicinal purposes.
Beginners – Avoid these strains!
The following strains are considered “advanced” and while they produce amazing buds, thy tend to be difficult to grow and/or finicky
Durban Poison – Tends to grow tall and shows a variety of unusual phenotypes, can be tough to clone. You don’t know what to expect when growing a Durban Poison seed. This strain originates from Africa and buds produce a unique “up” effect. Buds tend to be incredibly potent though not often “pretty” in the conventional sense with longer sugar leaves. Unusually quick to harvest, especially for a Sativa-leaning strain.
Jack Herer – Famous medicinal strain that is great for anti-anxiety, you cannot get the original Jack Herer strain as a feminized seed so you will need to buy regular (unfeminized) seeds and manually pick out all the male plants. Yields are on the smaller side but the quality of the buds produced are exceptional.
Liberty Haze – Genetics are not completely stable and many growers report different growth types with this strain. Can stretch tall in the initial stages of flowering, though does seem to respond well to supercropping. Unique flowery scent with citrus lime undertones. Unlike what breeder specs state, this strain needs about 10-12 weeks in flowering before she’ll be ready for harvest. When grown right, this strain produces thick dense colas with THC levels above 25%.
In fact , plants monitor their visible environment all the time. Plants see if you come near them; they know when you stand over them. They even know if you’re wearing a blue or a red shirt. They know if you’ve painted your house or if you’ve moved their pots from one side of the living room to the other.
Of course plants don’t “see” in pictures as you or I do. Plants can’t discern between a slightly balding middle-aged man with glasses and a smiling little girl with brown curls.
But they do see light in many ways and colors that we can only imagine. Plants see the same ultraviolet light that gives us sunburns and infrared light that heats us up. Plants can tell when there’s very little light, like from a candle, or when it’s the middle of the day, or when the sun is about to set into the horizon.
Plants know if the light is coming from the left, the right, or from above. They know if another plant has grown over them, blocking their light. And they know how long the lights have been on.
No one knows exactly how cannabis plants determine gender
Environmental sex determination is known to occur with cannabis plants. Many researchers have suggested that sex in Cannabis is determined or at least strongly influenced by environmental factors. Ainsworth reviews that treatment with auxin and ethylene have feminizing effects, and that treatment with cytokinins and gibberellins have masculinizing effects. It has been reported that sex can be reversed in Cannabis using chemical treatment.

A cannabis plant can grow taller than a tree in just one summer
Here’s an cannabis plant that produced 11 pounds 3 ounces worth of bud – grown in a 400 pound smart pot and filled with Vermisoil.
Look at the base of a cannabis plant this size, it looks just like a tree trunk with bark!
Cannabis seeds can germinate almost anywhere warm and wet
Life Finds A Way
“My friend accidentally grew this in her sink. How is this even possible?”
Seedlings have enough energy (“food”) stored in the seed to make their first set of leaves. After that, they need light and nutrients to grow further. Unfortunately, this seedling won’t make it unless transplanted to a more suitable growing environment.
