yea bud u got a hermie on ur hands, if the male flowers r just now poppin out at wk.8, depending on what kinda strain u are growing, seeds wont have time to form, let me be more clear, if u are growing a indica dominant or hybrid and plan on harvestin it within a week or so u prolly wont have to many formed seeds in ur bud, seeds take alittle while to form and become mature, now if ur strain is gonna flower longer ul prolly have a bunch of premature seeds in ur buds, now if this isnt the first pollen sack and there was sum that opened earlier and u didnt notice them then ul prolly have more seeds in ur bud, if its the only plant in the room then gently remove the male pollen sacs and keep a close eye for anymore and if u see anymore remove them but finish out ur plant, now if u have alota plants in that room id chop that hermie down today so u dont add anymore pollen on ur other plants, what strain is this? did u start from a feminized seed? also check ur room for light leaks cause even the tiniest light leak will cause hermies, iz all good tho brotha dont beat ya self up over it weve all had a hermie or two pop out on us, jus figure out what caused it and fix that problem before u start ur next grow
