I've never had hermie issues with BOGs gear and BOG is a good guy so if you're in the States he'd most likely hook you up.
Maybe you don't realize this but keeping and flowering in tiny pots like that will cause stress and stress flowers. What are those 1 gallon pots?
Sometimes when you have a system so dialed in and strong genetics the plants root system quickly maxes out its space so you need bigger pots than you'd normally use. There was another user in the Bodhi Thread that had issues with using smaller pots too, he realized that he had never had genetics that could max out his standard finishing sized pot and upped the pot size by two gallons and never had herm issues again.
This is not a breeding issue its nature. Good luck
