Cannabis leaves turning red

Another example of bright red stems that may be the result of a Phosphorus deficiency, or possibly direct light exposure.

Wet, compact soil or overwatering can trigger a phosphorus deficiency to appear even when all other factors are perfect. So make sure you water your plants properly every time to help prevent a phosphorus deficiency.
Sometimes accompanied by a Calcium deficiency, as Phosphorus and Calcium interact with each other in the plant.

Most nutrient systems that are formulated for a plant like cannabis will carry and abundance of phosphorus, especially in budding/flowering formulas, so it is unlikely that you will see signs of a phosphorus deficiency before other nutrient problems when using nutrient systems formulated for cannabis (as long as you keep your root pH in the correct range and prevent the plants from getting cold or being overwatered). If you’ve got very high powered lights, or if your plants are growing in direct sunlight, they may be going through a lot more phosphorus in the flowering stage than average and may need you to provide extra phosphorus to make sure buds get as big as they could be.
Cooler temperatures lower than 60°F (15°C), as well as large temperature swings, can make it harder for the plant to absorb phosphorus. Cannabis plants are therefore more likely to show signs of a phosphorus deficiency when the temperature drops too low, or if they go through a cold spell.
When there is a phosphorus deficiency, the lower (oldest) leaves turn dark green. Leaves occasionally get a bluish or bronze tinge, and may thicken or curl downward before exhibiting dark gray, bronze or purplish splotches. Sometimes the stems of the affected leaves will turn bright red or purplish, usually starting from underneath.
Your cannabis plant may show signs of a phosphorus deficiency if the pH at the roots is not in the right range. That is because when the pH of your root zone is off, your cannabis cannot properly absorb phosphorus through its roots. Therefore the first step is to ensure that you have the correct pH for your growth medium. Learn more about pH and cannabis.
Phosphorus is best absorbed by cannabis in soil at a root pH of 6.2 – 7.0. Phosphorus is best absorbed by cannabis in hydro at a root pH of 5.5 – 6.2. If you believe you have a cannabis phosphorus deficiency, it’s important to check the pH of your root zone to make sure the deficiency isn’t caused by the pH being too high or too low.

Phosphorus deficiencies can show up with the plant is having root problems or if the plant is overwatered, even if the pH is right and the phosphorus is there. Proper watering practices help plants grow healthy and avoid a host of problems!

Phosphorus deficiencies cause dark splotches on leaves and can appear at the bottom of the plant on some of the oldest leaves. Learn to spot & fix the issue.

A type of fungus that lives in soil, fusarium has the potential to kill cannabis plants.

Over-watering and under-watering have adverse effects on the plants. Too much or too little water can damage the leaves, stems, and roots of the plants. Good growers use strategies help them prevent over-watering or under-watering their plants.
Crickets and grasshoppers are everywhere. From flower gardens to farms, there is no escaping these terrible pests. Even worse, they have quite a big appetite for plants. Unless controlled, they might end up eating everything in the garden.

Using hard or soft water in the plants have their advantages and disadvantages.
As adorable as deer are, they can also be a menace. It so happens that these herbivores are attracted to cannabis plants. Unless the garden is fenced, they can come roaming freely and feed on the plants.
As mentioned, growing cannabis is a part of the fun that adds to the cannabis use experience. However, problems arising can be challenging. At times, the damage caused can not only be disheartening or discouraging but also cause one to quit cultivating.
Due to unequal distribution of nutrients because of complications brought on by diseases, damping off occurs. It results in weak stems that are soft and mushy. Unless rectified, it may cause the plant to topple and die.
A fungus can also cause verticillium wilt. The plants that attract this disease are the ones that are in grown in rich soil or those with stressed roots.

For outdoor growers, this animal is a friend and an enemy. First, birds are quite helpful in getting rid of pests like caterpillars and worms. But they can also turn out to be the enemy if allowed to touch plants during germination. That is because they happen to love eating seeds.

Cultivating cannabis is fun. For some people, growing itself adds to the experience of its use. Hence, in this article, we cover most of the likely problems cannabis growers may experience.
