Marijuana leafs

A leaf of marijuana, besides being a key component of the cannabis plant’s life support system, can tell a lot about the plant itself. In order to crop a healthy plant with fantastic buds, we must be able to read the signals that weed leaves send correctly. For example, if the leaves are yellow, you do not have to be an expert to figure out that something is not just as it is supposed to be.

Just as we sometimes don’t use words to express how we feel but rather change our behavior or facial expressions, our plants have a way of alerting us of their state. It is of great importance to be well informed. That being said, not only do we have to learn how to recognize the potential problem, but also how to solve it. Decoding the signals is crucial to taking appropriate measures to fix what is wrong.

Some of the most easily detectable sings are discoloration of leaves and yellow spots. However, the discoloration is not necessarily a reason to panic. Of course, always be on the lookout for mold, fungal spores, eggs, etc.

Some of the pests that attack cannabis crops are leaf miners (you can recognize them by white veins running through leaves) and leaf septoria (yellow spots will appear, but this particular pest is often thought of as nutrient deficiency because yellow leaves indicate it). The plants can also be attacked by spider mites, caterpillars, inchworms, etc. And if you are a proud owner of a cat, make sure you keep your plants out of the cat’s sight, do not learn to do that the hard way. 🙂

Types of cannabis leaves

Now that we’ve covered the basics on how to see if your plant is doing okay, we can talk about how the healthy leaves look like. Generally, three types of cannabis species are agreed upon. Sativa, Indica, and Ruderalis.

The height potential of Sativa plant makes it perfect for outdoor growing. It can grow up to 15 feet in some cases, but usually they grow from 8 to 12 feet tall. Sativa leaves are long and thin, and usually lighter in color, sort of a lime green shade. Some leaves can develop up to 13 “fingers”.

On the other hand, Indica leaves are wide and short, mostly with 7-9 fat “fingers”. Oversized leaves are typical for the heaviest Indicas of Afghan origin. Unlike the Sativa leaves, Indica leaves are darker in color, deeper shades of green. Also, Indica plants are much shorter than Sativa plants. They generally grow from 3 to 6 feet tall, and that makes them perfect for indoor growing.

Ruderalis leaves have the smallest number of “fingers”, only 3-5 of them. You could say they resemble the leaves of the young Sativa plants, only with less “fingers”. The interesting thing about Ruderalis leaves is that they have evolved to give auto-flowering cannabis the capability to blossom regardless of the hours of light it gets.

You can use the cannabis leaves in all sorts of ways, for example – making tea out of them. You can also dry and ground them so you can sprinkle them on your salads or pastas, or blend them with some other ingredients to make a smoothie.
