Symptoms of Over WateringDecember 7, 2018
The roots of a cannabis plant need water and air in order to uptake nutrients. Mediums like coco, and plants grown in hydroponics, do not usually suffer from over watering. This is because an air stone is used in hydroponics, and coco is light and airy, so plenty of air can get to the roots. If you plant is showing symptoms of over watering, in hydro, there may be an issue with your air stone.
Over watering in Soil
Most cases of over watered plants will be with plants grown in soil. Soil retains water for a lot longer than coco, so less air can get to the roots. If you do not let the soil dry out between watering, the roots can’t breathe.
What an over watered cannabis plant looks like
If your leaves constantly seem plump, and full of moisture, you’re probably over watering. The leaves are absorbing more water than they can sweat out. They become heavy, and will droop and curl under.
Over watering your cannabis plants will have an effect on their whole nutrient uptake. Your plants growth will be diminished, and you are more prone to getting mould and rot. You also run the risk of having bugs move into your grow room. Insects larvae like moist mediums. If your soil never dries out, bugs will move in.
How to avoid over watering a cannabis plant.
To avoid over watering a cannabis plant in soil, you have to let the medium dry out in between watering/ feeding. the top 2 inches of the medium should feel dry if you put your finger in there. The pot should feel light, and the medium should look dry.
There is a fine balance you have to find, which is specific for each grow, it will take practise on your part to get it right. Don’t let the medium completely dry out, as this will effect the microbes living in the soil.
Keep checking the weight of the pots, if you can lift it easily, water them. If you can’t, and it feel like there is weight to it, do not water them.
If you get run off after watering, remove it. Do not let your plants sit in waste water as this will also cause over watering. Remove run off immediately after feeding/ watering your plants.
Coco and watering
It is very difficult to over water when growing in coco. The coco doesn’t hold as much water as soil does. It runs straight through just making the medium damp. You can water every day in coco, and still not suffer from over watering.
If your plants show the symptoms of over watering, then you are most likely letting your plants sit in run off.
