I've been flushing for a week and a half so far for the coming harvest of my larger plants. Hoping these continue for a couple more weeks after the first batch is harvested. Lots of growing to do yet with this group. Tiny Buds so far.
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!
