Diagnosing Cannabis Plant Problems

By |abelle September 12, 2012 13349 Views Leave a comment Go to comments

All plant growers, including those that grow weed, would encounter at least once in their career as a grower a problem regarding the health of their plants. At first, it could be a challenge to pinpoint what exactly is wrong, and it might cause panic or the implementation of the wrong solution. 

That is why it is important to educate themselves (even before starting their plant gardens) with some of the most common plant problems they might come across. 

Different types of weed require different sets of nutrients for their proper growth and development. When cannabis reaches the vegetative stage, it will need specific types of nutrients, and when it reaches the flowering stage, it will another. 

So when diagnosing cannabis plant problems, experts advise to check the pH levels of the soil first before doing anything else. If it is below or over the right level, do something about it by applying additives that will increase or decrease the soil acidity. 

Otherwise, you can do the following steps to help you find out what is wrong. 

Look for bugs that might have been thriving in the plants for some time now. If there are several black dots that should not be on the leaves or branches, or if some of the leaves have been damaged, there might really be bugs in there. Lice, spider mites, aphids, white flies, thrips, slugs, snails, fungus, and grey mold are just a few of the most common infestations that occur in cannabis plants. 

There are different ways to get rid of them, depending on their types, so it is advised that you go and visit a pest company to help you with the best option to kill these pests. 

Now, if you notice that the plants’ leaves are turning yellow, this means that there is deficiency in nitrogen. This usually happens during the vegetative stage, and the best way to deal with it is to treat your plants with more phosphorus. 

If there are leaves that seem to twist or curl up, this might mean that there is too much light or there is insufficient air in the room. The solution for this problem is to get them away from the overexposed spot and move them someplace where there is proper air ventilation. You can then add magnesium and Epsom salts to aid in their recovery. 

Also, here are some nutritional deficiencies that you should watch out for: calcium, iron, boron, copper, manganese, molybdenum, nitrogen, phosphorus, potassium, sulfur, and zinc. 

If overall your plants just look horrible, you might have to replace the soil that you used and buy plant nutrients that contain the following: potassium, nitrogen, magnesium, calcium, phosphorus, and sulfur.
