To enable optimum growth in marijuana, the nutrient supply has to be lighter right from the beginning. Nutrient burn is one of the prominent issues that surpasses when an overabundance of nutrients is provided to the marijuana plant. The roots of the marijuana plant absorb excessive nutrients which result in the nutrient burn. Owing to the nutrient burn the tips of the leaves turn yellow or brown. The tips also appear burnt. It further progresses to curled and crunchy appearance of the leaves. Excess potassium results in the spotting of leaves around the edges and excess nitrogen causes downward curling of the leaves.
Choose the right amount of nutrients for every specific growth period. Plants consume water based on their growing conditions like temperature and humidity. Owing to high humidity, when a plant consumes more water that is overloaded with nutrients it results in a nutrient burn. On seeing the first sign of nutrient burn, supply the marijuana plant with pure water and allow it to utilize nutrients from the soil. Do not add extra nutrients to the water. A pure pH water thins out nutrients and prevents nutrient burn. This helps in recovery from the nutrient burn and also prevents its recurrence in new leaves.
The nutrient requirements vary during the vegetative and flowering stage. Flowering is the second stage in the marijuana plant which requires enough nutrients as well as it is susceptible to irreversible damage. Marijuana plants thus require more focused attention and gentle care during the flowering stage right before the harvest. A balanced nutrient supply is always better than a sudden overload. Make sure to take right precautions at the first indication of nutrient burn. Plants with high resilience are less susceptible to diseases, nutrient dearth, pest infestation and environmental stress. So choose the best marijuana seeds from a trustworthy plant dealer.
Temperature fluctuations have an adverse effect on the growth of marijuana plants. Both higher temperature and excessive humidity bring about signs of stress in the marijuana leaves. The leaves turn yellow or brown with spots and burns exploding up. Owing to a very high temperature, the leaves closest to the light source gets burnt or curls upwards. Higher the humidity greater the dehydration in marijuana plants. The plant growth slows down at this level. Taking the right preventive measures solves the problem at the beginning stage. Allowing proper ventilation into the growing room is the right key to solving such environment-related issues.
To maintain optimum humidity, utilization of a dehumidifier for a closed system is an ideal solution. The cold pipes of the dehumidifier condense moisture and reduces humidity levels in the room. But the use of a dehumidifier increases the temperature of the room. Adding air vents to humidifiers prevents the rise in temperature. To maintain optimum temperature, use of an air cooler proves to be a good solution as it evaporates water and cools the room. It does not increase the moisture significantly thereby offering increased efficiency during the growth of the plants. Large bulbs in the growing room emit more heat which can be removed to avoid excess heat generation.
