Imagine this: You’ve been nurturing your cannabis plants, providing them with all the love and care they need to thrive. You’re excited about the potential yield, but then you notice something alarming. The leaves are drooping, turning yellow, and the growth seems stunted. You rack your brain, trying to figure out what’s wrong. Then it hits you – you’ve been over watering your weed plants.

Cannabis Overwatering Signs

Overwatering is a common mistake, especially for novice growers. It’s easy to assume that your plants need constant hydration, but like all living things, too much of a good thing can be harmful. Overwatered cannabis plants exhibit several telltale signs.

The first sign is drooping leaves. Unlike the wilted leaves you see in underwatered plants, overwatered leaves are firm and curl in on themselves. This is because they are so full of water that they are forced to curl down.

Another symptom is a slowed growth rate. Overwatered plants may halt growth almost entirely due to the lack of oxygen accessible to the root system. This is because the roots, which also breathe air, can drown if they are constantly swamped in water.

Discoloration is another clear sign of overwatering. The leaves can start turning a light yellow color, a symptom that often confuses growers as it can also indicate a nutrient deficiency.

Will Overwatered Weed Plants Recover?

The good news is, overwatered weed plants can recover, but you’ll need to act fast. The first step is to reduce the frequency of watering. Wait for the top layer of soil to dry before watering again.

Ensure that each plant has adequate drainage. Water shouldn’t build up too much in the bottom of the pots or containers. Excess water should drain out of the containers, leaving the soil moist but not waterlogged.

How Do I Fix Overwatering?

If you’ve overwatered your plants, the first thing you need to do is wait until the soil is fully dry. Then, start using enzymes so that the root system grows strong and sturdy and can recover from any damage. Enzymes are catalysts that speed up chemical processes in your plants, helping to get rid of dead roots faster and making space for new, healthy roots.

Choosing the right substrate is also crucial. Your plant lives in the soil you choose for it, so it’s vital to choose correctly. Substrates that don’t hold water for too long are recommended, especially if you tend to have issues with overwatering.

How Often Do You Need to Water Your Plants?

The frequency of watering can vary due to different factors such as temperature, humidity, and the size of your plants. However, a good rule of thumb is to water your plants when the top inch of soil has dried out.

Keep in mind that the amount of water your plant can absorb may vary. A plant that drank a liter of water a week ago may only need half a liter the next week. It’s essential to monitor your plants and adjust your watering schedule accordingly.

Water Quality is Important

Water quality is paramount when it comes to growing cannabis plants. Cannabis plants consist of approximately 90% water, and water is required during various vital physiological processes such as photosynthesis and transpiration.

Before the growing process, check the quality of your water source. One important factor when it comes to water quality is pH. Cannabis plants tend to thrive at a pH of around 6.5. If the pH is either too high or too low, pH up and down products can be used to return it to normal levels.

Another important factor is PPM (parts per million), a method of measuring the amount of minerals that have dissolved into the water source. Cannabis plants prefer a PPM of around 500 during the vegetative phase and around 1000 during the flowering stage. Monitoring PPM is quite advanced, but it’s useful for ensuring your plants are getting the right amount of nutrients.

Water might also be contaminated with other factors such as pollutants and bacteria. Reverse osmosis filters are a great option to almost completely remove everything within a water source, allowing growers to add back only what they want their plants to come into contact with. Reverse osmosis filters are capable of removing between 95-99% of dissolved salts within a water sample and are therefore a standard method of cleaning water on an industrial scale.

Lastly, always monitor your water runoff. To produce healthy plants, you need to keep a close eye on the amount of nutrients your plants are receiving. Use trays to catch the runoff when you water your plants, and analyze both its pH and PPM. This will help you adjust your watering and feeding schedules as needed, ensuring your plants get just the right amount of water and nutrients.


Over watering weed plants is a common issue, especially for novice growers. However, with the right knowledge and techniques, it’s a problem that can be easily avoided and fixed. Remember, the key is to monitor your plants closely, adjust your watering schedule as needed, and ensure the water you’re using is of good quality.

Understanding the signs of overwatering, such as drooping leaves, slowed growth rate, and discoloration, can help you identify the problem early and take corrective action. It’s also important to know that overwatered weed plants can recover if you act fast and take the right steps.

The frequency of watering can vary due to different factors, but a good rule of thumb is to water your plants when the top inch of soil has dried out. And remember, not just the quantity, but the quality of water is crucial for the health and growth of your cannabis plants.

In conclusion, growing cannabis is both an art and a science. It requires patience, observation, and a willingness to learn and adapt. But with these tips on avoiding and fixing over watering, you’re well-equipped to grow healthy, thriving cannabis plants.
