Plant disease is a general term used when the condition of a plant deviates from the generally accepted norm. Even if you take care of your marijuana plants, there are things you might miss out on or simply forget. It will be more difficult for beginners to control all aspects of this plant as this is an entirely new experience. And, in the end, despite being careful, some things will happen to spite you.
Marijuana plants remain sensitive from start to finish. And the main problems that arise when growing cannabis are usually affected by various factors that we will discuss below. Check this guide to have a better understanding of cannabis disease identification.
Low Temperatures
There are chances that your weed strain has come through a lot before getting to you. This plant is used to hotter climates and adores warm weather even at night. Temperatures below 70°F (21°C) impair phosphorus absorption, which prevents plants from growing further. Plants get overcooled easily, but you can quickly spot this by the purple pigmentation on the leaves. If this happens, improve the conditions by stabilizing warm temperatures. To do that, you can use high-quality LED lamps.
Nutrient Burn
Sometimes growers try too hard and give the plant too many nutrients. Even the dose indicated on the package may be too much. Therefore, we recommend using only half of the daily dosage and adjusting it according to the situation. When burned, the leaves first become stiff and then gradually turn into golden brown. This leads to the death of the leaves. The way out of an emergency will be soil flushing. After that, it is better not to feed the plant until its state stabilizes.
Pests
Pests are a threat to all plants that grow outdoors. This environment is perfect for bugs because food is everywhere, and there are no predators. Sometimes a magnifying glass is required to spot these insects. In general, if you find tiny spots on the top leaves, then these are most likely pests.
And here is the main list of the main enemies of cannabis plants:
- Ticks
- Mushroom mosquitoes
- Whiteflies
- Thrips
Lack of Nutrients
A lack of nutrients in cannabis can also be detrimental to the plant, which is why we remind you of the importance of balance again.
Here are the signs of a lack of nourishing substances:
- Sulfur deficiency. The leaves turn yellow, and the roots become a distinct pink color. The most advanced stage means leaf laxity, as well as the presence of brown spots.
- Zinc deficiency. The leaves turn yellow, and the interveinal surfaces are filled with various pits or "pimples.”
- Phosphorus deficiency. This element is the primary plant nutrient, and its presence is critical. Lack of phosphorus means many flowering problems. Also, the growth of cannabis stops, the plant is dwarfed. Many leaves will turn brown, and some will develop purple and yellow hues.
- Potassium deficiency mainly occurs in open soil. It manifests itself in slower growth of the leaves, and the branches become very fragile.
Final Thoughts
It is critical not only to water and fertilize cannabis plants regularly but also pay attention to their appearance. When detected on time, the issue can be solved with minimal harm to your plants and crops. Thus, take measures as soon as you notice something strange with your marijuana.
