Check these first

  1. Ensure the plant is getting at least 6 hours of direct sun.
  2. Check if the plant is being shaded by taller plants or structures.
  3. Review your recent fertilizing habits.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The plant looks healthy but is stretching toward the light source. It is not producing any buds despite the season.

    What to do: Move the plant to a spot that receives full, direct sun for at least 6 to 8 hours a day. This plant will not bloom well in partial shade.

  2. Excessive nitrogen

    Possible

    How to tell: The plant has very lush, dark green foliage but no flowers. This often happens if you use a high nitrogen fertilizer.

    What to do: Switch to a balanced fertilizer or one with a higher phosphorus content to encourage blooming. Stop fertilizing for a few months to let the plant reset.

Stopping it coming back
