it does appear to be that way.
Look for some pollen sacks or nanners within the buds themselves to determine where the pollen came from.
If you have no males might be best to not use the seed as it may promote bad traits in the offspring.
Good Luck!
Possibly, possibly not.
The only way to find out is to take it off and look inside yourself.
Either way, it will not affect anything, but if it is a seed, you will most probably find more when trimming.
yeah it does look like like a seed on top of the bud. few seed can happen time to time, no need to worry if not much this won't impact significantly your harvest potency.
