Signs of overwatering cannabis

Firstly, the cultivator may simply be watering the plants to frequently and/or with too large a volume of water. This can be rectified by simply allowing the plant time to use the excess water around its roots and reducing the amount of water you have been offering. Some more experienced growers will simply assess the weight of the pot holding the plant and judge whether all of the excess water has been used up.

This drooping will likely occur after a watering, so remember to check back on your plants in the mnutes and hours after every watering to observe for signs of over-watering.
If you are spotting clear signs that your cannabis plants are over-watered, you need to decipher why. Generally, there are two reason as to why this occurs.

Eager to ensure that a cannabis plant is growing to its maximum potential, some inexperienced cultivators may water their crop a little to much. This can result in a number of problems, which can often set your grow back a number of weeks.
The other most common reason for over-watered cannabis plants is that your grow medium is not allowing enough air to get to the roots and/or has a poor drainage system. This can be altered easily by modifying the way in which your medium is set-up.
In some cases, chlorosis will occur in the leaves, meaning that they will turn yellow in colour. Don’t mistake this for nutrient deficiency; more often than not, if your leaves are drooping from the stem, it will be related to over-watering.
The reason that leaves will droop through over-watering is pretty simple. If there is too much water surrounding the roots, the plant is unable to take in enough oxygen. Therefore, the plant itself is being starved of this precious element, causing drooping and eventual death.
The first sign that you should be able to see from an over-watered plant is drooping of the plant. This is not concentrated to any certain part of the plant, it should be visible on most leaves and stems. It is also important to note that you are not looking at the tips of the leaving for drooping. An over-watered cannabis plant means that the entire plant will be curling and wilting from the stem to the tips of the leaves.

Under-watered cannabis plants often demonstrate the same symptoms as over-watered plants. While there is no definite way to tell between the two issues, common sense should prevail in this scenario. Even a novice grower should be able to tell if they have been too timid or too eager with their watering habits.

Signs of overwatering cannabis

Overwatering cannabis plants is a very common mistake in novice growers. It’s usually the result of caring slightly too much and providing an excess of a key resource. For some growers, the sight of slight dryness in the topsoil is enough to induce panic. It looks as though their plant is about to dry out and die, so they proceed by drenching the soil with too much water, too frequently.

One key piece of cannabis anatomy is the root system. As well as anchoring plants securely into the soil to prevent the wind from blowing them over, the roots act to absorb water and nutrients from the soil below. A little-known fact is that plants also use their roots to take in oxygen. If you give your plants too much water, or the correct amount, but too often, you obstruct their ability to intake oxygen, which then results in symptoms arising.
Seedling cannabis plants are particularly vulnerable, especially when it comes to watering—less is more at this crucial stage. Using a spray bottle, rather than a watering can, will help overzealous growers keep hydration under control. Give seedlings a light misting when the surrounding soil has begun to dry and your plants should flourish in no time.

Watering cannabis is a balancing act. Too much and you risk root rot, too little and your plant will dry out. Use these tips to fix any issues with overwatering and underwatering.
Pot size is also an important factor to consider here. You’ll need to start your seedling off in a small pot and gradually transplant it into bigger pots as it continues to grow in size. If you place a small plant into a big pot too early, the roots won’t be capable of taking in a lot of water from the soil, which means the medium will stay saturated for too long.
The remedy for overwatering is quite a simple one: ease off on the fluids! First thing’s first, leave more time between watering sessions. Probe the topsoil with your index finger and wait until the first 3cm have sufficiently dried out before applying more water. This will generally lead to a routine of watering around every 2–3 days. Additionally, during watering, make sure not to drown your plant each time. Water enough to notice runoff leaving the drainage holes for about 60 seconds after watering, and no longer.
Once a root system has developed, you can switch to watering routines that will see you all the way through to harvest. In line with the guidance above, watering should take place every 2–3 days, or when the surrounding soil is dry to the touch. The most effective way to get into good habits with watering is to water at the start of the day. For outdoor cultivations, plants will have an entire day of sunlight to utilise. If growing indoors, it is helpful to set your grow lights to come on at the start of the day, just as you are watering.
Underwatering can occur due to a busy schedule that forces a cultivator to forget, or it can arise in areas of high heat where watering is required more often. Underwatered plants will also appear to have an ill and weak look to them. Their leaves will be dry and droopy, and the tip of the plant may be bent into one direction.
