Does too concentrated STS cause inviable pollen? Despite dabking seeing "seeds all over", There were none. someone didn't get the joke. This fem seed run failed. Lower concentrationn gave 1000s, instructed concentration gave 100s, this OD gave zero despite 100% conversion.

Hey,
Yes, using too concentrated STS (Silver Thiosulfate Solution) can lead to inviable pollen even if you see full conversion to male flowers. Over-concentrated STS can damage the pollens viability leading to poor or no seed production as you experienced. It’s best to stick to the recommended lower concentrations for reliable results

Why the size difference?They are all treated the same way-PH/PPM have all been consistent the entire grow thus far. Is she just being stubborn and will catch up later? Is this genetics? Can I do anything to help her along - or just wait? She's nearly half the size of the other 2Plant. Other

Male or female?I need help from a professional. I would like to know why this is the only plant that is not producing flowers, and it is the largest, unfortunately it takes up a lot of space, so I would like to know if it is actually male or female?
