That's about how I would expect it to look, very nice. Good job brother.
I have my fair share of herm issues too. I know most are stress induced but fuck seems like shit will herm without much of an issue nowadays. I swear bagseeds 30 years ago were more stable than a lot of todays beans.
Grew in a hot garage in 93 with seeds saved from High school. Had no airflow, shitty lights and miracle grow and never had issues like now in my air conditioner, humidity controlled, well lit, co2'd, clean area with nutrients designed for cannabis.
I've had at least one plant throw balls my last 3 runs. Missed it last run and seeded everything.
As much as I love popping seeds wish I had access to cuts instead. Would also let me know if it's a me issue or genetic disposition to herm.
