Chronic under-watering can also lead to yellowing leaves and nutrient deficiencies. Plants that don’t have enough water often have thinner leaves and appear “lifeless”. Underwatering can also have negative effects on your plant as plants need water to survive. In addition, the leaves may be yellowing or show other signs of nutrient deficiency. Overwatered cannabis plants are typically droopy with leaves that curl downwards. This can be caused by both watering too much, as well as watering too often in some cases. Overwatering essentially results in the roots being drowned and can lead to root rot, which will quickly kill your plant as the roots are no longer functional and able to absorb water or nutrients. Both overwatering and underwatering can lead to detrimental damage for your garden. One of the second biggest causes of leaf discoloration or death is related to water intake. The resulting stress from inconsistent pH can cause brown spots to appear on the leaves. While most common in hydroponics, it can also occur in soil gardens. In some cases, deficiencies that may appear to be due to nutritional issues, can actually be caused by incorrect pH, which is blocking the plants ability to absorb what it needs. This is one of the most common reasons for leaf issues and/or death as improper pH can affect the roots ability to take in nutrients. One of the first things that should be checked if you notice anything odd about your cannabis plants is the pH level. Possible causes can include pH imbalance, over or under-watering of plants and/or nutrient deficiencies. However, there are certain cases where a deficiency can be a result of improper care or environment. Sometimes a cannabis deficiency is caused by stress and may clear up on its own once the stress passes.
