Overwatering is a common mistake when growing cannabis, though it ultimately comes from a good place. Of course, we want to make sure our plants are receiving an adequate water supply, but giving them an excess can turn out to be too much of a good thing.
Water is critical to plant health, but saturating your plant’s growing medium with water can lead to crispy leaves that may even begin to turn brown.
Water makes its way through your plants via osmosis. The cells work to pass on water to the next one. However, when too much water is travelling through a plant and it reaches the cells at the end of a line, they become too full and the cells rupture. This phenomenon can cause crusting at the tips of leaves, accompanied by a brown discolouration.
