Most Common Mistakes and Solutions


1. Excessive or lack of watering


Cannabis plants will only thrive on an effective dry and wet cycle. This means you have to water properly at the right time. So, what's the best way to tell if your cannabis needs watering? Lift the container when it's dry, lift it again after watering, and you'll know the difference.


When you come across a cannabis plant that can't be lifted easily, you can buy a hygrometer to insert into your growing container. System growers need to ensure that pumps, air stones, reservoirs and timers are set correctly from the start of planting. Need to check twice.


Solution: Monitor plant growth closely. This allows for a more accurate measurement of when to use water to prevent over- or under-watering from happening again. Too much water can cause root rot, and too little water can stunt plant growth. Keeping a plant growth journal is a good habit, and it's a must if you want to make money from growing cannabis.


2.pH and nutrients


Soil cultivation growers have the advantage of growing in medium, which acts as a buffer for the roots. Hydroponics and coconut soil are less friendly to pH imbalances. Even soil growers need to be at least close to the ideal pH of 6.0-7.0 and maintain it or the plants will suffer. 5.5-6.5 is generally considered to be the recommended range for hydroponics and coconut soil cultivation.


Basically, when the pH of your nutrient solution is above or below the specific requirements of your substrate, it prevents the complete absorption of all the elements in the solution. Plants stop growing due to lack of certain nutrients and micronutrients in the roots due to incorrect pH.


Solution: Use a high-quality pH pH solution and buy a pH pH test pen to automatically adjust a wider pH range. Rinse the plant with purified water, then dab it in the solution to get used to it. Also, make sure you're using essential nutrients that contain all the necessary micronutrients, taking into account the costs and budgeting for it.


3. Excessive or lack of fertilization


Likewise, plants need just the right nutrients at the right time. Read the dosage instructions on each bottle of fertilizer label before adding water. Additionally, we strongly recommend checking the website of the nutrition brand you are using, as most will feature custom charts and feeding schedules.


Solution: Rinse with purified water at the start of planting, then follow up with the manufacturer's recommended nutrient solution dosage for specific growth/blooming stages. Dosage should be gradually increased and plant behavior monitored before further increasing solution strength.


4. Excessive or lack of light


Indoor cannabis grows grown under artificial light must be perfectly positioned, and the lights must be at the correct distance above the canopy for optimal lighting. When the lights and reflectors are too close to the top of the bloom, the buds and leaves will turn yellow and brown due to too much light.

Conversely, too little light is usually a problem, most noticeable from the bottom up. Insufficient light causes shaded leaves or leaves that are too far below the light transmission capacity of the lamp to yellow and fall off.


Solution: Make sure to hang the grow lights according to the manufacturer's instructions. Adjust plant progress and use a tape measure to measure accurately. There are many new grow light technologies on the market today that have nuances, and you have to stick to the manufacturer's guidelines for positioning the light in the best position.


5. The growth environment is too cold


Temperatures below 10°C will cause the leaves of most cannabis leaves to turn yellow. Some growers even address this with purple and blue-hued grow lights. Of course, it only applies to the final growth stage of the plant, and it should be avoided in the early stages of plant growth.


Solution: Indoors simply turn up the heat or add more light to the grow operation and turn the negative into a bountiful harvest. Outdoor growers may need to bring plants indoors at night or at least consider building a greenhouse.


6. The growing environment is overheated


Overheating can cause cannabis plant leaves to turn yellow and dry out indoors and outdoors. Temperatures above 28°C prevent the cannabis plant from photosynthesizing efficiently and allow for looser and more airy bud formation.


Solution: Indoor growers need to turn up the air conditioner to make sure the water inlet and outlet are strong enough for the size of the grow room. Again, we strongly recommend consulting the fan manufacturer's website for performance specifications. Outdoors, the best growers can do is a simple shade to make sure the plant isn't growing too hot.


7. Pests and other animals


Obviously, bugs, microbes, and animals can harm cannabis plants.


Solution: Plant cannabis indoors as much as possible, and if it is outdoors, it is possible to prevent pests. It's impossible to 100% isolate bugs with outdoor planting, so do what you can. Grow cannabis in a quiet sunny location and use barbed wire to protect the plants from animals such as deer and rabbits.
