‘Nanners in late flower

Never seen this before and I need to know what to do. This is weird as fuck.

This pheno is on day 61. Big ass sativa dominant tangie. I wanted to give her 9 more days but I noticed some ‘nanners poking out of the tips of some of these calyx stacks today. I have a couple questions.

I have no light leaks, and this is the first time I’ve had a plant do this. If this wasn’t triggered by stress than I’m assuming this is genetic, but I thought ‘nanners tended to form on lower buds near the stalk where light penetration isn’t good. Not on the very tips of the buds. Can anyone give me an educated guess as to what caused this, i.e whether this is rodelization or stress herming.

Second question is if I need to chop her now or if I can pick the ‘nanners off with tweezers and let her finish. I can’t have hermie pollen contaminating my closet. I’ve got a really good HEPA cabinet for sterile microbial culturing and could suck all the pollen out of the closet with that, but this seems like a hassle. If anyone can tell me the best way to proceed I will really appreciate it. Here’s the pic. The ‘nanner is on the right side of the bud. There are a handful of them all over the plant but they haven’t dropped any pollen yet as far as I can tell. I watch my plants like a hawk and can guarantee they haven’t been around for long.

Here is one more pic, where you can actually see the ‘nanners coming out of the calyx instead of a pistil. This is fucked up, lol. The only reason I’m not completely freaked out by this is because I’m sure I caught it in time. I squeezed a bunch if surrounding calyxes with tweezers and I’m reasonably sure there are no seeds. I also want to confirm whether or not she’s rodelizing and if I should let the ‘nanners go.

Stress and light leaks or changes in the light cycle can cause nanners. Some strains are more susceptible than others and need more babying.

Nanners can release pollen the second they come out. But it may be sterile if you're lucky. I just cut my losses and chop them anytime I see a nanner. My wife likes the really early harvested buds so it's not a complete loss. She would like it if I chopped them all down early but that's not gonna happen, lol.

Right on. I’ll chop her down. My other phenos are under a week away from the chop so I’ll just go ahead and err on the side of caution. This pheno is already fucking stacked. I won’t lose too much yield by cutting her down now and since she’s my sativa daytime smoke I’m not too worried. The only thing that would really suck is if I squished some beans along with the bud and my rosin got contaminated with expeller pressed hempseed oil. I’ve had that happen a few times with dispensary bud. There have been no changes to the light cycle and the closet door gets shut once the lights go off. The only time it was interrupted was when I took the light down to install the bars. I took the light down an hour before it was supposed to go off and it didn’t turn on until the morning. I don’t do flash photos or look at them with the lights off so really I just want to understand why this happened. I’ve seen plants herm out before, but every time it has happened I’ve seen big male flowers and they’re near the lower parts of the branches. I’ve never seen, and never expected to see a ‘nanner coming straight out of a calyx like that.

So here’s my best educated guess now that I’ve started chopping her.

Number one, I need to be more diligent about closing the closet door. I know that with some phenos all it takes is a couple flashes, and others won’t herm even if the light cycle is totally fucked. I need to figure out what’s going on before I feel safe growing her outside.

Number two, upon beginning to trim her I noticed she foxtailed quite a bit, and pretty much every ‘nanner is coming out of a calyx near the end of a foxtail. I think I either need to tie her down better to the trellis or find a way to raise the light more, or both. They’re sitting on a cabinet in the closet and I could remove the cabinet.

Number 3, I know that to some extent this is to be expected with fem seeds from nirvana. I’m just sad it happened to such an otherwise awesome pheno. I’m going to try to lock shit down better next time, and next time is actually as soon as I cut these plants in the closet down and move the new ones in.

Number 4, I switched from HPS to my new LED halfway through the grow. Maybe the sudden drop in average temp and increased light intensity screwed her up. I will never switch lights halfway through flowering again.

This sums it up pretty well.

My Sunset Sherbert is more prone to nanners, probably due to the GSC in her. The first time I got nanners and chopped on day 28. That was actually my wife's favorite plant yet, haha. The second round I made it to like day 42, and my latest 3rd round made it to day 53 before I saw a nanner and chopped. My wife doesn't like the last one since a lot heavier. I still have another of the round 3 flowering, and it's day 66 today and so far no nanners on her. I didn't top this one or do any heavy stress training, and I think that is helping. Here she was Christmas Eve.

That’s good to know. So I still haven’t even been at this a solid year yet. I flipped my first plant in may and this is my first hermie. I try to stay really scientific about all of this and figure out what’s going on. This pheno is good enough that she’s worth the effort to get to, I’d guess, 75 days would be ideal. I made it to 61 but some of the nanners down lower were open and dried out. I haven’t found a single bean so far and I’ve trimmed thoroughly through a plant I harvested on Saturday. I’m staying cautiously optimistic.

I think switching to the LED halfway through and not being super careful about closing the door were the things that contributed. I don’t know what role way colder temps play but it was getting down into the low 50s and maybe even high 40s.

Speaking of science, I extracted and took a close up pic of one of the calyxes with both pistils and nanners. For science and knowledge.

I think this pheno is worth the effort. Absolutely amazing. Super frosty and will probably go all purple if she makes it to 75 days. Awesome chemmy orange smell and massive yields.

I think I should have kept tucking for longer. She scrogs incredibly well. I’ve looked pretty closely and I’m reasonably sure none of my buds got seeded. I think she started herming too late in the game.
