Cannabis root problems

If your plant is still refusing to come out, take a long knife and use the back edge to slide around the inner edge of the container. If your plant is so severely root bound that nothing will help to remove it, consider breaking open the container as your last option.

  • “Nutrient burn” without excess nutrients: If you spot the signs of nutrient burn, but you are feeding your plants only lightly.
  • Smaller buds with stunted growth: If your buds grow smaller, or your plants’ overall growth is slower than usual.
  • Sick plants, wilting, drooping: If your plants have a sick appearance or start to wilt or droop unexpectedly.

A healthy root system plays a vital part for your plants’ growth. After all, it is with their roots that plants take in water and nutrients.

In severe cases of root bound plants, you may not be able to loosen the root ball with your fingers alone. You will then have to prune the roots to free them. By using a sharp knife, cut a few top-to-bottom incisions into the outer layer of the tightly-packed root ball. But be very careful and only cut thin roots. Do not cut any thick tap roots! 2-3 incisions evenly spaced out around the root ball should be all that you need to free the roots so that they can grow outwards again.
Most cannabis cultivars, at least in colder climates, grow indoors in a tent or in a dedicated grow room. Growing indoors in containers means there is the risk of your plants becoming root bound. When this happens, it can lead to all sorts of growing problems. Let us take a closer look at what “root bound” means. Learn how to recognise the signs, so you can fix the issue and prevent it from happening in the future.
When you have managed to pull out your root bound plant from the container, the roots will be running in a tight circle in the shape of the container. The roots are trapped and unable to grow freely any longer. Before you replant into a bigger container, you should try loosening the compact mess of roots so they can spread out again. You can carefully do so with your fingers.
Your previously root bound plant is now happily sitting in its new and big container, but it is going to be quite sensitive for some time. To help it to recover from the transplant shock, you should keep stress levels low for a few days. Feed it only lightly and if you can, turn down your lights a notch or two as well. You will know that your plants have fully recovered once you see new, healthy growth. When this happens, which can take between a few days to a couple of weeks, you can return to your normal lighting and feeding schedule.
You want to be careful when you remove plants from their containers in order to not damage the roots.

Cannabis root problems

The process is very straightforward: irrigate your plants with plenty of water to flush away any nutrients retained in the soil. If your plants received large doses of nutrients during flowering, you’ll need to flush them properly for about two weeks. If, on the other hand, you used lower doses of fertilisers during the last few weeks of flowering and your plants are already showing yellow leaves, you can be a little less rigorous with flushing.

The roots are the first organ of the plant to come into direct contact with the surrounding growing medium after germination. Most plants have three types of roots: the main tap root and the fibrous roots, which grow into the ground, and are often invisible to the naked eye; and adventitious roots, which can sprout from the aerial parts of the plant, such as the stem, and grow towards the substrate.
For this reason, it’s crucial to respect the proper wetness and dryness cycles during the entire growth period in order to get a powerful and vigorous root system capable of absorbing large amounts of nutrients, eventually resulting in a large plant with amazing bud production.

Flushing your plants is a simple process that it’s vital in order to harvest high-quality buds free from any nutrient excesses that could alter its taste and smell.
After a few days, the upper leaves will become weak and droopy, as if in need of some water. The death of the plant may be imminent, and there’s hardly anything that can be done to save it, as the roots are already in a very bad condition.
This is a common problem among growers who don’t have the correct substrate for cannabis cultivation. It should be noted that a specific substrate may be suitable for one type of plant, but not for others. If you use the wrong substrate your plants will grow very slowly, lanky and with sparse foliage. They will also be more likely to suffer from problems associated with overwatering or during a period of drought.
The cannabis plant has all three types, but the adventitious roots are less common and only grow in environments with high and steady humidity levels. The ability to produce adventitious roots is what makes cannabis so suitable for propagation via cloning.
It could be said that the root, or root system, has a pyramidal structure. The main tap root grows vertically down into the soil, and its secondary offshoots spread themselves throughout the substrate. In turn, these secondary roots develop small offshoots, called capillaries or simply root hairs, which are responsible for the collection and transportation of water and nutrients for the entire plant.

After a prolonged lack of irrigation, the leaves will be droopy, which is a sign that the roots are slowly becoming dry and dehydrated, as are the capillaries responsible for water absorption.

A successful harvest depends to a great extent on the condition of your plants’ roots. In this article you’ll see the most commonly found problems wit
