Check these first

  1. Touch the top 2 inches of soil to check for dampness.
  2. Inspect the drainage holes to ensure they are not blocked.
  3. Look at the undersides of the leaves for any signs of pests.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The soil feels constantly soggy and the lower leaves turn yellow and soft.

    What to do: Let the top 2 inches of soil dry out before watering again. Ensure your pot has drainage holes so excess water can escape.

  2. Nutrient Deficiency

    Possible

    How to tell: The leaves turn a pale yellow while the veins remain green.

    What to do: Apply a balanced liquid fertilizer diluted to half strength every 4 weeks during the growing season. This helps replenish the soil nutrients.
