Boron Deficiency In Marijuana Plants
Boron deficiency is rare for marijuana plants, and occurs almost exclusively in western soils when it does happen. It is primarily indicated by the browning or graying of growing tips and then their subsequent death. The lateral shoots will begin to grow after that, but then they will eventually die as well. These shoots will look sunburned, gnarled, and will have a bright green coloration. Brown necrotic dead spots will show up on the leaves, and the area around them will be composed of dying tissue. These deficiencies are similar to a lack of Calcium, but Boron deficiencies are unique in that the necrotic spots they produce are smaller.
Petioles (leaf stems) and the main stems of the marijuana plant will be brittle and potentially hollow. Boron deficiency targets exclusively newer growth, meaning that it is “immobile.”
Eventually, the roots will stop growing and the secondary roots will also shorten and become swollen. Fungal and bacterial attacks are more common as the roots become more vulnerable.
Overabundant Boron is started largely by over-fertilization. Leaf tips will turn yellow and start curling inward. Eventually, the leaves will fall off and the marijuana plant will die.
It’s important to keep the Boron levels stable, because it affects a number of different processes within the plant including:
- Pollen germination
- Seed production
- Cell division
- Protein formation
- Healthy leaf color
- Plant structure formation
Ideal amounts of Boron will maintain the strength of stems, stalks, and branches. It also helps calcium stay soluble.
There are a number of ways to treat Boron deficiency, but it’s always best to avoid the problem in the first place. Using something like Marijuana Booster could certainly help your cause. It contains all the necessary micro nutrients a marijuana plant seeds, including boron. If you run into a Boron deficiency, you can also treat the water solution with a single teaspoon of boric acid per gallon of water. For quick relief, try borax, compost, compost teas or Marijuana Booster.
