Leaves hang down no matter what i do in Coco Coir.

Potassium (K): Potassium influences water regulation and turgor pressure within cells, affecting the rigidity and flexibility of the cell wall.

Introduction: Unveiling the Secrets of Negative Pressure in Cannabis Negative pressure, also known as tension, is a crucial phenomenon in the world of cannabis plants. It plays a pivotal role in the efficient uptake and transportation of water from the roots to the various parts of the plant. Let's delve into the captivating world of cannabis physiology and discover the power of negative pressure. Understanding the Mechanism of Negative Pressure in Cannabis Negative pressure in cannabis plants, similar to other plants, is created through the cohesive and adhesive properties of water within the plant's vascular system. This mechanism relies on the ability of water molecules to form hydrogen bonds and adhere to the walls of the xylem vessels. Understanding the mechanism behind negative pressure is essential to grasp its significance in cannabis physiology. 1. Cohesion-Tension Theory: Driving Water Uptake The cohesion-tension theory explains how negative pressure enables water movement from the roots to the leaves of a cannabis plant. As water evaporates from the leaf surfaces through stomata, a tension is created, generating a suction force that pulls water upwards through the xylem vessels. This process relies on the cohesive forces between water molecules, forming a continuous column for efficient water transport. 2. Xylem Vessels: The Plumbing System of Cannabis In cannabis plants, xylem vessels serve as the conduits for water transport. These specialized cells form interconnected channels that allow water to move upwards from the roots to the leaves. The negative pressure generated through the cohesion-tension mechanism helps drive the water flow within the xylem vessels. The Significance of Negative Pressure in Water Uptake for Cannabis Negative pressure plays a vital role in the water uptake and overall health of cannabis plants. It ensures a steady supply of water for essential physiological processes, including photosynthesis, nutrient uptake, and structural support. Let's explore the significance of negative pressure in water uptake within cannabis. 1. Ensuring Proper Hydration and Turgor Pressure Negative pressure facilitates the movement of water from the soil, through the roots, and up to the leaves of cannabis plants. It helps maintain proper hydration and turgor pressure, ensuring the cells remain firm and upright. This is crucial for healthy growth and structural support. 2. Facilitating Nutrient Absorption Negative pressure not only transports water but also aids in the uptake and transport of dissolved nutrients within the cannabis plant. As water is pulled up through the xylem vessels, essential nutrients and minerals are transported along with it, supplying the various tissues and organs where they are needed for optimal growth and development. Environmental Factors and Negative Pressure in Cannabis Several environmental factors can impact the generation and functioning of negative pressure in cannabis plants. Understanding these factors is crucial for cultivating cannabis in different growing conditions. 1. Humidity Levels and Transpiration Rates Humidity levels influence the rate of water evaporation from the leaves of cannabis plants, which directly affects the tension and suction created within the plant. Higher humidity levels can reduce the rate of evaporation, potentially impacting the negative pressure and water transport efficiency within the plant. 2. Temperature and Water Availability Temperature plays a role in the rate of transpiration, affecting the water loss through the leaves. High temperatures and limited water availability can increase transpiration rates, potentially leading to higher tension and suction within the cannabis plant. The Power of Negative Pressure in Cannabis Physiology Negative pressure, or tension, plays a crucial role in water uptake and distribution within cannabis plants. By understanding the mechanism behind negative pressure and its significance in water transport, cannabis cultivators can ensure proper hydration and nutrient absorption for healthy and robust plant growth. Paying attention to environmental factors that impact negative pressure can further optimize the cultivation conditions for thriving cannabis plants.

droopiness like that can be from over watering but if the other ones are fine its likely nothing. I see a lot of people using the 30% perlite and 70% coco coir as a ratio for good aeration in the mix and to aid in drainage. Make it much harder to over water when it drains well. Good Luck!

Some plants just have droopy leaves, no matter what. As long as she keeps growing, there is nothing to be worried about. It is not a cal/mag issue. Water to run off every time you irrigate in coco.........aim for at least 10% run off each time.

Hello mate, i see all the info in your diary so you did all in the rigth way, i only advice to be sure the pH solution is rigth at 6.2 for the coco coir, as far as I know with this substrate you need to keep the pH lower than the soil. However, your problem, i think, is linked to the amount of water they need, if you have a tool to check the soil humidity, use it! Good luck and happy journey!!
