Are these nanners?

One of your plant should be stressed and tuned hermy

Yep, male flowers.

That's a pollen sack that contains anthers (nanners). This is much, much worse than a "nanner." Single nanners don't have a full compliment of anatomy, so they often don't produce a ton of pollen some are even impotent. A pollen sac has a full compliment of anatomy, and even if it is a hermie with slightly reduced pollen production by comparison to a true male, that 1 sac can cause a lot of seeds, and usually you don't just get 1 sac. If you catch them when they are a "pod" and sealed up, you can avoid pollen from the sacs. I'm not suggesting you keep a plant popping pollen sacs, though. Throw it out unless the damage is already done. If it is already pollinated, look into making ice hash (bubble hash). It's a sieving process, so you will 100% avoid the seeds and get something from your grow. Quality is diminished relative to prevalence of pollination per plant.... more seeds, more reduction to quality.

That sucks bro. Nothing says 'surprise' like a hot chick with a dick.

OHHH mate. But looking back at your weeks your plant is ruined. The THC in this plant will be very low. Still? There'll be some. But, most of the energy will go into making seed, not thc. You'll be able to tell seed pods..I bet you crack a few open you'll see em. Cut all that out. I ride out it out. You'll get some bud, lots of seeds. When switching from veg into pre flower autos you gotta watch, check part of the plants. 90% of the time if you catch them quick you can cut them out. As they look like where bracts grow. (You can also get nanners that grow in the bud) as a female grows these pods..calyxs. but, they are made up of the good owl thc and then you got your leafs mixed in. But, look close at how bud grows. They're built up on lots of pods. Sadly most of yours will produce seeds. I can see that even with this new upgrade.

Yup this is a hermie buddy this is not inviting news for me as i have 3 biscottis from zamnesia that are flowering atm sorry to see i hope its happend late. you never know if its a false hermie though sometimes you can get sacks and then little to no seeds cause the pollen is not fertile so it cannot pollinate the pistils ive had that once before. i hope this is the same for you buddy best of luck in what every you do :) Looking at the bud I'm really sorry to say but that mostly looks like seeds I think you know this already though :( Sorry buddy Ive hadto gut 25 plants before due to this. its not fully wasted if you can make hash and concentrates out of it :) on wards and upwards buddy people say that the main cause is light leaks so i would thoughroughly go through your grow area and look for any cracks or anything it only take 0.002 micros of light to disturb a cannabis plant in slumber.
