I was just turning my plants today and I noticed one had something that looks to be pollen sacks right at the spot I topped it about 2 weeks ago. Luckily, its the only one showing these signs, so I just pulled it out of the grow room for the time being. I inspected the entire plant, and it seems that the spot in this picture is the only one where its growing what looks to be the sacks. They seem to be in the early stages if they are in fact what I think they are, I pulled one off and it didn't seem to have any pollen inside. The plants are growing under a 400w MH, 18/6 light schedule in dirt. Here's a picture of the area in question. What do you guys think?
