1. Over Watering And Under Watering

Problem: 

If you’re a new grower, then underwatering and overwatering can be the two most common problems in your cannabis growth. Underwatering your marijuana leaves can make the leaves droop and slow down their growth. 

Now, if you’re overwatering the plant, you will make the leaves curl downwards as they will become tight and rigid with excess water. This will slow down the growth process of your plants, and if not fixed quickly, it may even cause root rot. 

Solution: 

If you are facing the issue of underwatering, you will have to water them more often and give them more quantity than before. However, it shouldn’t exceed the average level. You can provide quick watering in the drooping leaves to make them stand back within half an hour. 

In case of overwatering, you will have to limit your use of water. The best way to determine the timing to water is by checking the dryness of the soil. If the soil is dry all the way around and an inch deep, you can water the plant. 

2. Nutrient Burn In The Plants

Problem:

Whether you’re a new or an experienced grower, you will face the issue of nutrient burn quite often. This mostly happens when growers get too excited and overfeed their plants. 

Nutrient burns usually occur when you feed your plants with too strong a mix of nutrients or feed them excess nutrients frequently. You can identify this issue when your leaves will turn brown and crispy as if they have been burnt. Also, you will notice a rapid decline in the growth of your plants. 

Solution:

If you notice burning at the tip of the leaves, take it as the early sign for nutrient burn in your plants. You have to immediately hold off the feeding to your plants for a couple of weeks. 

Then, you can continue to feed them nutrients in the proper quantity. This way, you can flush out the excess nutrients from your plants without much effort. 

3. Light Burn In The Plants

Problem:

If the top of your cannabis plants comes too close to the indoor grow lights, your leaves will turn yellow and burn. You can easily identify this issue by checking for the leaves that are close to the light-medium. You can notice yellow coloration in the leaves, especially the ones at the top. 

Solution:

If you face the problem of light burn, you will have to uplift the lights by six inches to one foot higher than before. However, the distance between your plants and the grow lights depends on the stage of your cannabis growth. You can check for the manual along with the lights to determine the ideal distance for the lights. 

  1. Wrong pH Level

Problem:

One of the most common reasons why growers experience issues with their marijuana leaves is growing it at the wrong pH level. You must mix the nutrients and water at the right pH level to get the desired growth results. 

If you follow the wrong pH range for your cannabis plants, you may end up with nutrient lockout. This means your plants will be in a state of shock and become unable to absorb any nutrients for the time being. 

Solution:

So, if you feel that the plants are facing nutrient deficiency, ensure to check if you are using the right pH level or not. A pH level between 5.8 and 6.2 is ideal for your cannabis growth. 

  1. Toxicity And Deficiency of Nitrogen

Problems:

Nitrogen is one of the essential macronutrients needed by cannabis plants for optimal growth. If you see a nutrient booster or supplement for your cannabis plants, you will notice the name of three macronutrients, namely Nitrogen, Potassium, and Phosphorus. If your cannabis plants face deficiency in potassium, you will see the leaves turn yellow and die. 

If you feed too much Nitrogen to the plants, it will result in Nitrogen toxicity, also known as ‘The Claw.’ This other name is given as the leaves eventually curl or claw downwards. Also, your cannabis leaves may turn dark green, indicating that there’s nitrogen toxicity in your plants. 

Solutions:

You can fix the issue of deficiency of potassium in your cannabis plants by checking the pH level at first. Ensure that you’re using the correct pH range for your plants. If you are, then you can add a nutrient booster to the plants that are enriched with nitrogen content. Moreover, if you are looking forward to fixing nitrogen toxicity, you have to reduce the amount of nitrogen mix in the nutrient feeding for the plants. 

6. Spider Mites: A Damaging Pest Issue

Problem:

Spider mites are not a common issue, but when they happen, they cause significant damage and make it difficult to deal with them. The best chance to get rid of these pests is to eliminate them at an early stage. These pests, along with others, prefer to hide on the underside of the leaves of your cannabis plants. 

These mites crawl and nibble around the leaves like a spider. Also, it is hard to notice them with naked eyes. If you see tiny and light-colored spots underside the fan leaves, you can consider them the early sign of mites. 

Solutions:

You must ensure to monitor your cannabis plants daily and comb the leaves after every couple of days to easily pot pests or mites. You can take the help of a magnifying glass to have a close look at these pests. 

However, the best solution is to buy live ladybugs from a gardening store. This organic option will help you to get rid of the mites as the bugs will gulp them. You must kill every mite in your plants to eliminate them from having further reproduction. 

  1. Aphids Attack In Cannabis Plants

Problem:

Aphids are tiny organisms that feed and thrive on the underside of the fan leaves of your plants. They are green in color with long legs, just like a grasshopper. Similar to mites, these organisms also crawl around the leaves.

However, these aphids are more harmful as they suck all the nutrients and water out of your fan leaves. This may result in your leaves wilt and die. 

Solutions:

Firstly use a magnifying glass to find these aphids in your leaves. You can use ladybugs to kill the aphids. So, buy ladybugs from gardening stores, and leave them on the leaves to eat and eliminate the aphids from your plants. 

You can also use a neem oil mix and spray it over the area affected by aphids. However, you must use this spraying method only if the matter is extreme, as any spraying can cause mold and rot in your cannabis buds. 

Final Thoughts 

So, by now, this guide must have given you the required details about the seven most common problems faced by cannabis growers, along with the solutions to fix them prior to any severe damage.
