One day late on my weekly update. Currently in the middle of my "Tripple D". Defoliate-Darkness-Dry. All Fan leaves have been removed, any yellow or dead leaves have been removed. No water in 3 days. Heading into 2 days of darkness and will harvest on Christmas! YEAH!
Hey!
Sorry to say but it seems so... Looks like a genuine pollen sack.
I saw you have other plants in there, if your intention isn't breeding i'd go ahead and get that fellow out of there!
Good luck and happy growing!
