I harvested a CBD Crack plant by Fast Buds a month ago,found some nanners in it,also found some very immature seeds.No light leak,no harsh conditions,no stress and it was all green till the end.But this happens...I won't be using them as they are too immature but to be honest I don't care about seeds in my buds.I just throw them away unless I know they are useful.And yeah,I noticed them at harvest
