I'm not going to try and scare you in anyway so take this with a grain of salt. I grew 5 of those alien og from cali connection. Week 2-3 of flower they all hermied on me. I had to chop em down. As many have mentioned before you can cut the pollen sacs off and keep close eye on the plant. I didn't have the luxury of time on my side so I had to dispose of them or risk the rest of my plants at the time. I just posted the other day on another thread from a guy that was asking about is alien og from CC and his had hermied also.
I was enlightened from the community that it's not a guarantee by any means and could just be coincidence. It is pretty know cali connection have great strains but also use disingenuous breeding practices.
I'm not saying by any means this will happen to you but as with any plant you should always check the sex in early flower everyday. It's easy enough to watch one plant and manicure the sacs off and I hear many have had success in doing so diligently.
All in all looks just like mine was....great! I wish you good luck sir! Looks like you've got a handle on what your doing.
