1 Plant Scrog I Chemdog Green House

Havent fed her, since she seems pretty much fed with nitrogen. Orgatrex seems to be a bit heavier on the Nitrogen so i will try to leave it. Buds are getting big, sadly i found one Bud with a pollinated Calyx. I dont know where it is from. The plant is totally clean from any Herms she didnt do that in any way and i checked twice a Week since in Bloom. My assumption is Pollen that was trapped inside the Room or my Fans. Something is happening here but i dont know the cause yet. I checked her for an Hour but couldnt find anything. It just seems a bit weird to me. But hey like my last grow as long as i can grind it up without any issues iam fine with seeded Buds. ^^ She is getting 3.5 Liters every 2 Days. Update and new pictures after 2 days: Shes doing pretty good she is drinking a bit faster now i might really need to water daily soon. I also want to lower the light even further.
