Small Seeds in whole crop

Hello,

I did some work on my lighting a few weeks ago, and now noticing small seeds in all my plants. There are 4 groups of plants that went in to flower at different times, and so far I have found the small undeveloped seeds in all my plants.

I have some that are mature and ready to come out, and the seeds are still small and immature.

I also grow alot from seeds. I have not seen any total males or mature seeds. They are all very small and green.

Did this come from me screwing with the lights? They were never in total dark while the lights were on, but I did unplug a light leaving the others on.

Any ideas?
Thanks

Are they seeds or staminate flowers? Or both? Sounds like you have a hermie on your hands.
