Update 20.12:
Well, I couldn’t have been more wrong thinking everything was going well. One of my plants is forming seeds all over, which obviously means it came into contact with male pollen. I have no clue where the pollen came from—either I accidentally brought it in, or it entered while we were letting fresh air into the apartment.
I’ve checked all of my plants thoroughly and couldn’t find any “bananas” or other signs of hermaphroditism. But this plant is absolutely full of seeds, so I’ll be doing an emergency harvest tomorrow. It’s not going to improve THC-wise, so there’s no point in waiting.
Another plant has around 4–8 buds with visible seeds as well. I’ll be cutting those buds off too. This couldn’t have happened at a worse time; I really needed a solid harvest from this grow. I just hope the other plants don’t get affected further.
I’m also worried about the plant sharing the same base in the Autopot system as the seeded one. It might not get water properly now. What a disaster—rip.
