Overwatered Weed Plant Recovery and Prevention

Growing weed requires all-rounded care - the lighting, temperature, humidity, etc., and what we are going to talk about today, watering. One of the most common mistakes first-time growers make is overwatering cannabis, consequently, leading to a host of problems such as root rot that can severely impact your weed plants. To tackle an overwatered weed plant, you need to act fast. So, no more chitchat and let’s dive in. 

Identifying Overwatered Weed Plant

Overwatered weed plants exhibit several telltale signs to call for help. One of the most common indicators is yellowing cannabis leaves, particularly the lower ones, which signal that the plant is receiving too much water. Despite having ample water, the plant may also appear wilted or droopy, a condition that often confuses weed growers who mistakenly believe the plant needs even more water.

Additionally, overwatered plants tend to show significantly slowed growth. This stagnation is due to the roots being deprived of oxygen, which is essential for their proper functioning. Root rot is another serious issue caused by overwatering, leading to a foul smell and brown, mushy roots that can severely damage the plant’s health.

Cannabis leaf curling is another symptom, where the leaves curl downwards or appear swollen as a result of the waterlogged conditions. Overwatering can also create an environment conducive to moldy weed or mildew growth on the soil surface or the plant itself, further harming its health.

Another sign of overwatering is edema, where water-soaked blisters or bumps appear on the leaves due to an imbalance in water uptake. Finally, overwatered weed plants might shed leaves prematurely as a stress response, leading to a noticeable decrease in foliage.

To sum up, you can identify an overwatered cannabis plant by the following signs: 

  • Yellowing Leaves
  • Wilting
  • Slow Growth
  • Root Rot
  • Leaf Curling
  • Mold or Mildew
  • Edema
  • Dropping Leaves

Best Solutions to Fixing an Overwatered Weed Plant

When your marijuana plant reaches a stable stage such as the vegetative phase, occasional overwatering does little harm to it. However, seedlings and young cannabis plants are particularly vulnerable to overwatering due to their delicate and developing root systems. If you spot any signs of overwatering, take immediate and strategic actions to help it recover. Here’s how we deal with an overwatered cannabis plant. 

  1. Stop Watering Immediately: The first step is to stop watering the plant and let the soil dry out completely before the next watering session. Check the bottom of the flowerpot to see if there’s any water pooled. 
  2. Improve Drainage: Ensure that the pot or growing medium has adequate drainage. If the plant is in a pot, check that it has enough drainage holes to allow excess water to escape. 
  3. Change the Soil: Inspect the roots for signs of rot. If there are, you may need to repot the plant using a well-draining soil substrate to enhance water movement. Or, you can mix perlite or vermiculite into the soil to improve aeration and drainage.
  4. Adjust Watering Schedule: Review and modify your watering schedule. Watering cannabis only when the soil feels dry to the touch up to your first knuckle or when the pot feels lightweight. You can even use a moisture meter to check soil moisture levels before watering.
  5. Add Enzymes in Water (Optional): Using enzymes when watering cannabis plants strengthens the root system by quickly breaking down dead roots into sugars that the living roots can absorb, promoting the growth of new, healthy roots.
  6. Remove Damaged Leaves: Trim away any yellowed or damaged leaves to reduce stress on the plant and allow it to focus its energy on new growth.
  7. Reduce Humidity Levels: High humidity can exacerbate overwatering issues, so you should decrease the humidity level in the grow room to save overwatered cannabis.

By following these steps, you stand a big chance to help an overwatered weed plant recover and thrive. Be patient, as it may take some time for the plant to fully bounce back.

How to Prevent Overwatered Cannabis 

Basically, how to prevent overwatered weed plants equals how to water marijuana perfectly. We gathered some tips and effective strategies to avoid overwatering:

1. Always Check Soil Moisture Before Watering. For soil-grown cannabis, insert your finger into the soil up to the first knuckle. If the soil feels dry at that depth, it's time to water. In coco coir, aim to water every 1-2 days. Note: the top inch of the medium doesn't need to be completely dry before the next watering.

You can also lift the pot to gauge its weight. A lightweight pot indicates that the soil is dry, while a heavy pot suggests that it’s still moist.

2. Water Gradually: Pour water slowly and allow it to seep into the soil evenly. This helps prevent water from pooling at the bottom of the pot, which can lead to root rot.

3. Environmental Control: Maintain appropriate humidity, temperature levels, and air circulation to reduce the risk of overwatering. High humidity can exacerbate overwatering issues, so keep humidity moderate. Proper air circulation helps to dry out excess moisture in the soil and prevents mold and mildew growth.

4. Use the Right Container Size: Ensure that the pot size is appropriate for the plant. Too large a pot can hold excessive moisture, leading to overwatering.

5. Watering Tools: Use tools like watering cans with narrow spouts for precise watering, preventing over-saturation of the soil.
