Underwatered Cannabis Plant and How to Fix It

Watering your cannabis plants is an important part of growing, but it’s also one that can be easily forgotten. When you’re busy checking on your plants and handling other tasks in the garden, it’s easy to forget about watering—and this is when mistakes happen. In this blog post, I’ll talk about what underwatered cannabis looks like and how to fix it so that you don’t experience this issue yourself!

Underwatered cannabis plants are a common problem for new growers, especially during the first few weeks of a plant’s life. This is because when you’re just getting started, it’s easy to accidentally forget about your plants for too long or not give them enough water in general. Luckily, if you’ve underwatered your cannabis plants, there are some simple steps you can take to fix the problem.

Symptoms of a Cannabis Plant That Is Underwatered

If you have a cannabis plant that is underwatered, it will show the following symptoms:

  • Leaves are drooping
  • Leaves are turning yellow or brown
  • Plant is wilting or not growing
  • Roots are not growing or turning brown/dead

If your plant is experiencing any of these symptoms, there’s a good chance you’re under-watering it. It may also help to know that if your roots don’t grow well, then neither will your plant!

How to Fix an Underwatered Cannabis Plant

If you’re underwatered and have to fix your plant immediately, here are some tips on how to do it:

Water your plant.

If the soil is dry, water it with 1/4 cup of water per gallon of soil (or 2 teaspoons per 1-gallon pot). Don’t add fertilizer yet – wait until after you see signs that the plant is recovering from being underwatered.

Add fertilizer, but don’t overdo it!

It’s best to add just enough to keep the plant healthy without making him/her too happy. Fertilizers can sometimes make an over-watering situation worse because they encourage fast growth; so adding fertilizer in this case may backfire on you and cause further damage to your plants!

Use a hygrometer

(You can buy one at any gardening store) if possible so that you know exactly what kind of humidity level is present in each room where cannabis grows; this way when humidity levels get too low or too high above 70% then there might be trouble brewing down below ground level! Unless otherwise specified by manufacturer instructions – usually around 80% RH – then feel free as a weed grower nowadays with air filters / humidifiers/dehumidifiers etcetera as long as those three things work together well together within reasonable limits: like don’t use a dehumidifier while also having an open window nearby allowing cold air drafts inside which would lead directly into growing area where temperatures might get too cold when combined with colder temperatures outside coming indoors through open windows due outside temperature drops due lack outdoor air circulation caused closing all doors except for main entrance door leading back outside again.”

What Not to Do When Underwatering Your Cannabis Plant

  • Do not give up on your plant.
  • Do not give up on the health of your cannabis plant just because it is underwatered.
  • Do not just throw away your plant and start over with a new one, even if you think it’s dead.

The good news is that it’s not too late. Here’s what to do.

Now that you know what an underwatered plant looks like, it’s time to diagnose the problem. The good news is that it’s not too late. Here’s what to do:

Remove the plant from the soil

Take your time and be gentle. If there are any roots attached, leave them alone for now; you can cut them later if necessary. You may want to break up some of your dirt immediately so you can see what’s going on inside your container better—but be careful not to damage any roots or stems in the process!

Remove any dead leaves or buds

For this reason, some growers actually cut off all their plants’ leaves before transplanting them into new pots (more on this later).

Remove any dead stems

Roots and trimmings from around those places where they meet together (like at joints between branches). This will help prevent mildew growth by giving air circulation access where needed! Some people also recommend removing these pieces after every watering session…just keep doing it until no more discoloration appears after each one.”


We hope that this article has helped you understand what can happen if your cannabis plant is underwatered, and how to fix it. Remember that while this is a common problem (and one that can be fixed) there are many other problems that can affect the health of your plant. Be sure to keep an eye on its overall health and look for signs of trouble such as yellowing leaves or wilting stems before deciding that it’s time for intervention!
