One answer “Why are the leaves of my Do-si-Dos autoflower plants turning yellow?

  1. Yellow leaves on a Do-si-dos autoflower can be a sign of nutrient deficiency or overwatering. While it’s normal for the leaves on your Do-Si-Dos autoflower plants to yellow off as they begin to flower and mature, it’s important to take a closer look at the leaves and determine what the cause is before it affects your entire crop.

    Nutrient Deficiency

    When plants are deprived of essential minerals, their leaves will often turn yellow because their growth is stunted and it takes longer for the new leaves to produce chlorophyll and turn green. This can be caused by a number of things, such as soil that’s low in nitrogen, phosphorus, and potassium, or a wrong watering or feeding schedule. Denying plants most or all of their needed nutrients can lead to nutrient deficiencies cause yellowing first of the older leaves and eventually the entire plant.

    To diagnose a nutrient deficiency, examine the type of yellowing and its location on the plant. A light yellow on the oldest leaves may be a nitrogen deficiency, while a yellow on the edges of the leaves may be potassium or phosphorus. To fix nutrient deficiency it is important to use the correct nutrients for your specific plants and to follow the manufacturer’s instructions for adding them to the soil. It’s best to start by using a quality soil that’s been enriched with all essential minerals.


    Autoflowering plants are much more sensitive to overwatering than to underwatering. If the soil is too wet and soggy, it becomes hard for the plant to absorb oxygen which can cause the leaves to yellow. You can tell if overwatering is the issue by feeling the soil; if it’s wet and soggy, it’s time to scale back a bit on watering. To fix the problem, allow the soil to dry out slightly and remove any water from the tray or pot. Only water your plants when the top half-inch of soil is dry.

    Other Possible Causes

    Other possible causes of yellowing leaves include too much or too little sunlight and too much wind. Too much direct sunlight can dry out your plants and cause them to yellow, and too much wind can cause water stress and cause yellowing. Allowing your plant adequate amounts of indirect sunlight and avoiding direct wind will help to keep them healthy and happy.

    In conclusion, it is important to take a closer look at the leaves to determine what is causing the yellowing and then take the appropriate steps to prevent it from continuing. Understand that autoflower plants are more sensitive to overwatering and nutrient deficiency than many other plants. Ensure that your soil is the correct pH and that you’re providing the right amount of nutrients and water to your plants. Lastly, make sure that your plants are getting the right amount of sunlight and make sure wind isn’t a problem. Following these steps should help to ensure that your Do-si-dos autoflower plants stay healthy and productive.
