Two things brotha and I have dealt with ALOT of hermies! I can spot them fuckers from a mile away! You my friend have a MJ plant that looks to be on the airy side, buds wise. Not bad or anything just looking at it it looks that way. Now some of my Sativa dom plants tend to grow buds like that, the clylax will swell up bigger than shit looking like a seed is in there, when you unravel the whole thing you will find a tinny tinny "seeed" looking thing. To be flat out honest, if you haven't seen a Bannana and there are no balls you are good. And your plants looked close to being done, even if you had one plant go hermie on you now it would take weeks to form seeds. If you are worried about the clones, then you will have to get some close up pic's. I don't seee anything to be concerned about in your pic's!
It is good to keep a close eye on your plants, I think you are seeing something that isn't there. trust me, when you have one Hermie in your grow room you will NEVER forget what those pieces of shit look like!
