Actually I meant the opposite. The more seeded those coloas are or the whole plant is for that matter, the longer and smaller the seeds seem to be. Not that Ive noticed any differences in seed size being a contributing factor to identifying select plants. But the more the plant is seeded the more work it has to do to mature all those beans. I run my females after they have been seeded with a medium fertilizer regiment, and no need to boost the Phos like you would if your growing sensimillia. Definately keep the N and K in the regiment and don't cut them out.
So yes, you can overload a plant with male pollen and what I generally see is alot more white seeds that dont mature properly along with the majority of what the plant is producing. But ultimately in the end, it doesnt really matter Medusa, this is all just the small stuff when it comes to breeding. Seeds are going to come no matter what. Its the selection process that is the key to it all. And feel free to pick my brain anytime Medusa :)
