Why aren't my autoflower plants producing buds?Updated 21 minutes ago

If your autoflowering cannabis plants aren’t forming buds, there are a few common reasons — and most are fixable with small adjustments. While autoflowers don’t rely on light cycle changes to trigger bloom, they still need the right conditions to start stacking flowers.

1. Plant Age

Autoflowers usually begin flowering 2 to 5 weeks after sprouting. If your plants are still young, it may simply be too early. Give them time — you may see pre-flowers soon.

2. Light Quality and Schedule

Even though autoflowers don’t require 12/12 lighting, they still need strong, consistent light to thrive.

• Ideal schedule: 18/6 or 20/4

• Weak or insufficient lighting can delay development and reduce yields.

3. Nutrient Imbalance

Autoflowers are sensitive to feeding schedules, especially during the transition from vegetative to flowering stages.

• Too much nitrogen can prevent or stall bud formation.

• As soon as you see pre-flowers, switch to a bloom nutrient with lower nitrogen and higher phosphorus and potassium.

4. Environmental Stress

Stress can disrupt an autoflower’s internal clock and delay flowering. Double-check for:

• Overwatering or underwatering

• Poor drainage or rootbound containers

• Temperature extremes (below 60°F or above 85°F)

• Improper pH levels or nutrient lockout

• Signs of pests or disease

If your plants are healthy and over 5 weeks old with no signs of bloom, feel free to reach out with your grow details — we're happy to help troubleshoot and get those buds forming. 🌿
