Not saying it's not possible but I've never had that issue. My plants veg 18/6 under CFLs and get transplanted to the flower chamber under 600HPS 12/12 all in one day. In my recent crop the power was out on 3 different days and I had to run my flower chamber with 1 80W CFL for about 6 hours on those days and still no hermies. It could be that those genetics are particularly unstable and the change in light intensity is enough. If that's the case not sure I could work with them unless it's something amazing. As others have mentioned might be time to try some new strains? I hope you get it sorted quickly.
