Over – Watering

Over-watering has got to be the most common reason that results in leaves to curl up. What happens is that overwatering will drown your plant’s roots, and the crop’s way of telling you that it is waterlogged is through droopy and curled up leaves. You might think that such an outcome can only be due to dryness, but I suppose you might be undoubtedly wrong because over-hydration is also the culprit. Aside from that, persistent watering despite signals of excessive waters can invite parasites such as Pythium, which could rot the roots. Even though your chosen cannabis plant is resistant towards force, algae and fungi can still colonize it, and worst is, it could also destroy it.

The Solution for Over-Watering

Through over-watering, not only can it make cannabis leaves to curl up, but it could also unwantedly invite water molds, which are microorganisms that destroy a plant. You have to take counteractive measures to ensure that those microorganisms won’t ask themselves on your plant. To do this, you have to maintain a wet-dry system. The cycle consists of dehydrating your plant but not entirely, and you will only water it once it’s already experiencing weight loss. 

Afterward, administer the post-watering behavior of your plant, and when it seems to worsen, reduce the volume of water. Also, you can do the alternative way by making long intervals in between the watering schedule. As much as possible, make sure that it won’t acquire Pythium because it is incurable and will vastly affect your roots. 

Over-Fertilization

Since over-watering is deemed as dangerous, expect an over-fertilization to be the same. Likewise, heavy fertilization is also not advisable. An excessive amount of vegetative growth rich with nitrogen can make the leaves to claw and curl. At times, some circumstances go canoe. The heavy approach towards the application of phosphorus and potassium, especially at its flowering stage, can leave the plants to dry. Chlorosis and discoloration are the most usual symptoms that could happen in both cases. 

The Solution for Over-Fertilization

A reminder that in this solution, the feeding approach is not a great option, and it is ill-advised by experts because cannabis plants have a different reaction towards fertilizers. But, that doesn’t mean it’s already a hopeless case because you can still do something. What you need to do is to star low and slow. By definition, it means momentarily increase your doses only when the leaves are no longer curling or clawing. However, diving into the increasing period right away and disregarding signs can make the leaves curl extremely, die, and drop-off, something you do not want to happen. As usual, pH levels play a vital role in this solution. You have to maintain the precise level with the soil, which is at 6.0 and 5.8 at the hydroponics system.

Drop-in Temperature

Severely hot temperatures can also be one reason why cannabis leaves are curling up and looking brown and unhealthy. The said indications are distress signals sent by your cannabis plant. Note that cannabis plants are unlike other regular ones because they can use only photosynthesis at specific temperatures, which are only up to 28 degrees Celsius. Above and below can cause harmful impacts.

On the other hand, outdoor growers will experience heat waves drought and is a controllable factor that could affect the crops. What outdoor growers need is a screen shade that will prevent leaves from acquiring direct heat from the sun. If you have scorched leaves, there’s nothing you can do to revive it; instead, you will have to eliminate older foliage. Furthermore, one solution is to have your crops in a white pot to make it more relaxed.

Rise in Temperature

If there’s a drop in temperature, there’s also undoubtedly a rise in temperature that could serve as a reason as to why cannabis leaves are curling up. In this problem, growers will most likely notice all kinds of discoloration in their leaves. The said issue is due to the prolonged exposure of a cannabis plant to below 10 degrees Celsius. The worst it could do is kill your plants. Moreover, a contribution of relative humidity in its high state could allow botrytis and other fungi to arrive in your plant.

The Solution for Rising in Temperature

During Indoor growing, if you are sensing that the temperatures are dropping, you will have to add more lights to add heat. To know if this is indeed happening, you will have to monitor the environment at all times. Outdoor growing will require you to perform early harvesting movement, and if possible, you should transfer the plants indoors during the night.
