Cannabis is a hardy and adaptable plant, thriving in various climates around the world. Its ability to grow almost anywhere has earned it the nickname “weed.” However, despite its resilience, challenges often arise during cultivation, whether you’re growing indoors or outdoors. From pests and poor weather to nutrient imbalances and overwatering, many factors can hinder your plant’s growth.
Identifying Problems in Your Cannabis Plant
When cultivating cannabis, you may encounter a variety of issues. For example, if the leaves begin to lose their vibrant green colour, it’s often a sign of nutrient deficiency. Tiny dots or webbing on the leaves can signal the presence of pests, while stunted growth may indicate a problem with the roots.
Common Mistakes New Cannabis Growers Make
Even experienced growers encounter challenges, but beginners often make a few key mistakes. Here’s a look at two of the most common:
1. Overwatering
One of the most frequent errors new growers make is overwatering. Cannabis plants don’t need constant watering, and in fact, their roots require dry periods to properly absorb oxygen from the soil. Overwatering can prevent this process and even lead to root rot, as the soil doesn’t dry out enough between waterings.
To avoid overwatering, check if the soil is dry about 1-2 inches below the surface before watering again. Letting the plant dry out slightly encourages stronger root development.
2. Excessive Nutrients
Another common misconception is that more nutrients will lead to faster growth and bigger plants. However, overloading cannabis with nutrients can have the opposite effect. If a plant receives too many nutrients, it may experience nutrient lockout—a condition where the plant is unable to absorb more nutrients, leading to deficiencies and poor health.
Instead of adding too much, aim for balanced feeding. It’s better to provide too few nutrients than too many since correcting a nutrient deficit is much easier than dealing with excess nutrients. Organic nutrients also offer more flexibility, as they are generally gentler on plants. Don’t forget to monitor the pH of your water to ensure proper nutrient absorption.
Cannabis Plant Health: What to Look Out For
Regularly inspecting your plants is essential to catch problems early. This can be especially effective during pruning sessions when you’re already closely examining your plants. Here are a few key things to look for:
• Stunted Growth: If one plant is growing slower than the others or appears unusually small, there may be an underlying root issue, such as root binding. Roots need room to grow, and if they are restricted, the plant will not thrive.
• Leaf Condition: Healthy cannabis leaves should be a rich, deep green. If you notice yellowing, discolouration, or spots, this is a sign that something isn’t right. It could be a nutrient deficiency, pH imbalance, or pest issue.
• Dead or Damaged Leaves: Regularly remove yellowing or dead leaves, as they no longer serve the plant and can attract pests.
• Bugs and Pests: Inspect the undersides of fan leaves, as this is where pests like spider mites often hide. Additionally, check around the base of the plant at the soil level, where root aphids may lurk.
3. Mould and Bud Rot
During flowering, look for mould and bud rot, as these issues can ruin your harvest.
By staying attentive and proactive, you’ll be well-equipped to address problems before they get out of hand. Cannabis plants are resilient, but they’ll thrive even more with the right care.
