Watersanswered grow question 6 years ago I noticed you have stopped feeding p and k. Maybe this is why bud production has slowed. Try a pk boost and run it a little longer than you would have. If the plants don’t have access to the same strength of light, or if one is slightly more in the peak zone of true watts then that could account for the airy buds. Keep moving your plants around in the tent so that each branch and plant has a chance to reach its full potential.
