Cannabis Nutrient Burn: Prevention and Treatment

Cannabis is such a special type of plant that needs special care and attention, too. That’s why beginning growers take their time to learn the right process of growing their crops and try other strains that are less complicated to grow. Cannabis nutrient burn is one of the common problems that cannabis growers, both new and expert, encounter during the entire growing process.

Even expert growers are not exempted from this since many of them want to make sure their crops receive all the necessary nutrients they need. However, the problem is when there had been too much of this and that already put into the plants. Nutrient burning then occurs.

What is Cannabis Nutrient Burn?

Nutrient burn happens when the plants become stressed due to excessive feeding of nutrients. It’s a mistake that most new growers with less experience and those who are very eager to see healthy buds showing up. They tend to over-feed, thinking that they are giving the best care and concern for their beloved buds.

But, the good news is that this problem can be reversed back to the plant’s normal and healthy condition, especially when the problem has been detected before it becomes worst. Plants, no matter how much you want them to absorb as many fertilizers as possible, they can just have enough and then get overdosed after that. Without the right balance in the soil where they are planted, the entire growth of the plant becomes disturbed, and they suffer until some of them start to die.

Factors That Lead to Nutrient Burn

Various reasons cause a nutrient burn to occur in crops aside from over-feeding that some growers tend to forget and overdo. Some of those factors causing nutrient burn are the following:

Strong nutrients mixed into one – younger or seedlings that have just been planted suffer from this condition more than the mature ones. If you are not someone who knows how to use fertilizers mixed in one, it would be better to just leave the plants alone and just do what you know is best for them. Mixing products of different kinds also don’t make a good impact on plants.

The soil has been left too dry already. This is one reason why watering your plants regularly is very important. Letting the soil dry up for too long is not good. When water is gone from the soil, there shall be an increase in the concentration of fertilizers in the soil, too.

Abuse of bloom-boosters is not advisable as well. They have chemical properties like phosphorus and potassium that, if too much, become a cause of your crops’ illnesses. However, you can use such fertilizers but with the right dosage only because they are also very effective in enhancing the quality and size of the buds.

Abuse of stimulants for growth. Even though they help with pushing the cannabis plants during the vegetative stage, still, the use of it should be moderate and just enough for the plant’s needs.

Signs and Symptoms
