Issue: If your plant is sagging, then it’s normally an indication of either over or under-watering.
Skip the over/under-watering of your cannabis plants and DIY your own cannabis hydroponics system.
Marijuana Underwatering Signs
- sagging (plants typically improve after being watered)
- leaves typically appear “papery” and thin due to the fact that they don’t have any water inside them. (This is opposed to overwatering where the leaves typically feel
puffed up and “fat” from all the water consisted of inside) - persistent underwatering ultimately causes yellowing leaves and nutrient shortages
If your soil or soilless medium looks bone dry each time you water, or if you understand that your roots have actually dried, than avoid best down the the service area, as you certainly have a case of underwatering.
Under-Watered Marijuana Seedlings – Leaves feel papery and thin, growing medium is dry
If it worsens…
The cannabis plant in the middle is under-watered, triggering it to sag. Due to the fact that it was taller and straight under the grow light, it ended up being underwatered despite the fact that it was getting the very same quantity of water as its brother or sisters. Often you’ll see indications of under-watering instantly after updating your grow lights (if you don’t alter your watering routines), due to the fact that all the plants begin consuming more due to the additional light and heat.
Persistent Under-Watering (Under-Watering regularly)
The majority of growers tend to provide excessive – not insufficient – water to their plants. Nevertheless, if you’re investing extended periods far from your cannabis plants or the containers are drying up in less than a day or 2, it might suggest that your plant requires to be watered more frequently, or be provided more water at a time.
It’s likewise typical to under-water when plants begin overgrowing their pots, or if growers get on a schedule of offering a particular quantity of water rather than taking notice of the soil.
- plant might require to be watered more frequently
- plant might require more water at a time
- plant might have overgrown its pot and require to be transplanted
It can be hard to identify persistent underwatering due to the fact that issues might appear like nutrient shortages. One huge idea is that plants liven up each time after you water.
Chronically Under Watered Seedlings – These yellow leaves are really triggered by the plants being somewhat under-watered regularly
The curling/clawing and charred ideas on the following 2 plants might appear like it might be triggered by another issue, however in this case the signs are the outcome of the plant being frequently under-watered
Notification how the leaves are clawing and ideas appear charred alomost like nutrient burn. It’s occurring due to the fact that the plant isn’t getting
enough water regularly.
The leaves near the buds of this male marijuana plant began turning yellow. In this case, the grower identified it was due to the fact that the plant had actually overgrown its pot and was consuming more than anticipated, and as an outcome the soil was getting too dry in between waterings.

Unsure? If you’re uncertain whether your plant requires basically water, how do you find out precisely why your plant is sagging?
1.) Determine: Is my plant over-watered?
A marijuana plant does not get over-watered due to the fact that it’s provided excessive water at the same time – overwatering is triggered by the plant being watered frequently, or if the plant does not have correct drain (which indicates the growing medium is taking too long to dry).
2.) If not over-watered, does my plant have root issues?
Growing hydroponically? When you see indications of wilting and overwatering in a plant that is growing hydroponically with the roots in water, normally that’s a sign of a root issue like root rot.
In reality, all marijuana plants can often show wilting/drooping signs that are really the outcome of root issues.
3.) You might be seeing signs of under-watering
So if you check out the brief description in action 1 about what triggers overwatering (and you’re sure you haven’t overwatered your marijuana plants), and you’re specific you’re not seeing indications of root issues, than your marijuana plant may be sagging or wilting due to the fact that it requires more water.
If you’ve been underwatering your plant, its leaves will look limp and lifeless, like these plants.
Signs of underwatering are the same for plants in soil or soilless growing mediums like coco coir or perlite.
Option: Don’t wait till leaves sag to water your potted marijuana plant! It’s good to let your plant dry a bit after watering. But, always water your marijuana plants again before the leaves start sagging.
This is true for plants in both soilless mediums and soil.
Newbie growers often overwater their plants. But, underwatering happens too.
So you’re quite sure your plant is under-watered. A thirsty marijuana plant will perk up quickly after getting water.

How to water marijuana correctly (for soil and most soilless mediums)
- Wait Till Plant Requires Water – Wait till the top of the growing medium is dry about a half inch deep (as much as your first knuckle). Avoiding the topsoil from staying damp for too long can also help avoid bugs like fungi gnats. Some growers use the “lift the pot” method to check when plants need water. They lift the plant to see if it feels light from lack of water. For coco or very high-drainage mediums, water a bit earlier when the top starts to dry. This is because it’s harder to overwater in these environments. If you keep having trouble with underwatering, you might need to water more often. This could be because your pot is too small, your plant is rootbound, or because of temperature or humidity.
- Water till you get a little overflow. If using nutrients in the water, add water till you see 10-20% extra overflow water drain out the bottom of your pot. This helps avoid nutrient buildup in the soil. It also makes plants grow faster. If not using added nutrients, just water till you get a little bit of overflow. This way, you’re not rinsing out your nutrients. But, make sure you’re soaking your medium well – you don’t want dry spots in the soil!
- Return to step 1. If water doesn’t come out quickly or pots take more than 5 days to dry for step 1, you might have a drainage problem. You might need to give less water at a time until your plant is drinking more. If pots dry in just 1-2 days, you might need to give more water at a time, or transplant to a bigger pot.
An easy way to tell if a potted plant is ready to be watered is to pick it up. If it feels heavy or not, you’ll know.
As plants use up all the water in their pot, it will get lighter. You can use an extra pot filled with growing medium for comparison. This extra container represents the ‘dry weight’ of your growing medium. If your potted plant feels just a bit heavier than your dry pot, it’s time to water. After a while, you’ll get a feel for how heavy your plants should be. You might not even need the extra pot anymore.

If your plant has “the claw” and not just normal drooping, you might have nitrogen toxicity (too much nitrogen).
