they’re still early to mid-flower, so the buds have time to bulk up. Here’s what matters for outdoor bud density Phosphorus & Potassium Once you’re in flower, dial up your P and K. Those are the nutrients that build bud mass. If you’re not feeding bloom nutrients, that’s your first move. A good P:K ratio helps pack on weight.
Sunlight Outdoor buds get bigger with more direct sun. Make sure your plants aren’t shaded by anything. Full sun all day = fatter buds.
Stress management Don’t stress the plants unnecessarily. No overwatering, no nutrient burns, no heat shock. Stress = smaller, airy buds.
Genetics Some strains just naturally make smaller, airy buds no matter what you do. If yours are prone to that, you’re fighting uphill. But most strains will fatten if you give them the right nutrients and light. Time They’re not done yet. Let them finish. The last 2–3 weeks of flower is where most of the bulk happens.
Keep feeding them right, give them full sun, and be patient. The density will come.
