Germ disclaimer would mean a super thick husk on the seeds. Nice proper scuff and soak and this should be no problem.
It is an OG crossed to an OG, so of course some testers are going to find some balls. So we are talking male flowers on female flowers. However, this can be worked around easily by cutting all lower nodes that don't get GOOD light, a little bit trickling down is not enough. You just want tops, but don't go trimming after 14 days in flower, try get it done in the first week. You will have zero problems.
If you do get a boy bit here and there, don't freak out, just pluck it and watch that node. I just remove the node. If the balls are high up on a cola, YOU HAVE A LIGHT LEAK. Even a tiny one, but it is there. Other types might handle that, but not OG.
The other thing, is to not flower from seed. Mother up your seed plants and flower CLONES. Clones are usually as stable as you can get even if the mom made a few balls. If I like a mom, I will take two of her babies and replace her with them, if I like the second run I will keep 4 small moms eventually so if I feel like a run it is a week or what before I have the shoots I need, if I want to go SoG 4 mums are more than enough for a 4 week rotation, even 2 weeks should work fine.
To be fair, if ONE tester got ONE ball, they will say it is slightly unstable. But an OG head will work with them just fine.
