There are other environmental factors which can stress a plant into a sex conversion. This includes as a reaction to insects or disease. It can also occur with the use or overuse of certain kinds of pesticides and fungicides.
However, since this is a problem that will not disappear during the growing process, here are some guidelines for checking your grow.
Such stress includes changes to hours of darkness during flowering, dramatic changes in temperature, drought and physical damage.
However, this tendency is also considered to be a sign of inferior plants. A good mother plant will not show signs of hermaphroditism even when subjected to this kind of stress. All cannabis can turn, but high-quality genetics will resist the urge the most.
Female plants take a bit longer than males to show signs of gender after flowering. The plants begin to develop a few wispy white hairs where the buds will soon grow. These flowers begin to form between the stalk and stem. Female pistils are always white (never green).
Regular cannabis seeds are usually about 50% male and 50% female. The female plants produce bud cannabis. Male plants produce seed pods. They can also produce tiny amounts of THC via trichomes on the leaves. However, if you are not growing your cannabis as a science experiment don’t mess with male plants. It is a waste of time.
Determining the gender of your cannabis plants is the first step to a successful grow. Female plants are the only ones that produce bud cannabis. While it is fairly easy to spot the gender difference, cannabis does come with a curveball. Plants can also be hermaphrodites. And female plants can switch to this state during growing stress.
The first answer is an established breeder. The best way to start with an all-female crop is to buy the feminized seeds from an established source.
Male plants literally have grape-sized “balls” of pollen. The balls will show up about a week or two after the plant has entered the flowering stage. They also produce a growth that is a distinct yellow colour and look a bit like bananas.
Cannabis plants have two genders – male and female. However female plants can also become both genders in order to pollinate. Here's how you tell the difference
While both result in pollen production, true hermaphrodites produce sacs that need to rupture, while anthers are exposed, pollen-producing stamen.

Pre-flowers can initially be extremely small and hard to identify with the naked eye, but you can use a magnifying glass to get a better look. Examine the nodes of the plant and look for either the early growth of small sacs on a male, or two bracts on a female, which will eventually produce the hair-like stigma.
Seeded buds are generally regarded as low-quality cannabis. When seeds are present, the smoke is harsh and unpleasant.

When a female plant develops both male and female sex organs, it is considered a hermaphrodite. This means your cannabis plant is now capable of producing pollen that can pollinate your entire garden. “Herming out,” as some call it, is something that generally happens when a plant becomes excessively stressed. Some plant stressors include:
This is important for a breeder to achieve new genetics, but most growers remove the males to allow females to produce seedless buds, also called sinsemilla. These are the resinous buds that appear on the store shelf; they all come from female plants.
Though there are other methods to determine what sex the plant is, examining pre-flower formation is the most reliable.
Because this occurs when cannabis is under stress, it’s important to monitor plants after they have been exposed to stressors—indoors: high temperatures or light leaks are often the cause; outdoors: a snapped branch might be repaired and then turn into a hermaphrodite.
Determining the sex of your cannabis plant is vital to achieving your growing goals. Luckily, sexing cannabis plants is easier than one might think.
