I don't know about the buds being smaller (or less potent), but it's true that a lot of the plant's energy goes to developing seeds. What is also definitely true is that the yield will be smaller. Given two buds of the same size, one with and one without seeds, which one is going to give you more smokable material? A fully seeded bud can have half its weight in seeds. In other words, an oz of seeded bud might contain only 1/2 oz of actual bud and 1/2 oz of seeds (more or less).seeds require alot of the plants energy. I notice that buds are much smaller on heavily dusted plants. I imagine that what ever energy goes to the seeded preflowers is energy that is not gonna go to the buds, so I believe it would reduce bud size on the entire plant. How much? Probably not that much. a few seeded preflowers is nothing to a healthy plant.
