Let’s talk nanners/hermie

[Tsubaki30]

I run the proline this charting as I mention I round off the numbers and balance the main flora trio
The additives all stay the same via the chart

I run the aggressive feeds as I am dialled and a powrful

You get nicer end product when you don’t push plants to their limit with nutrient strength, but if you use GH’s Light Feed then it’s in ok range already. but it’s always better to read the plant and adjust EC accordingly and not just go by what a feeding chart says.

Just mind the amount of Nitrogen in your feed, dial it back bit by bit after the stretch ends and you will get smoother smoking buds in the end.



If you have your growing style working well for you and your set up is dialed in and you have good eamount of experience with all of it, then it’s time to stop following a ready made feeding charts and start playing around with the nutes your using and start making your own npk nutrient feed mixes - low enough Nitrogen levels during bloom and how to gradually shave N down after stretch ends. And then how to get a nice fade on your plants before harvest by lowering EC gradually during the last 3-4 weeks before the chop.

This bit of knowledge and skills is where the real magic happens regarding marijuana growing – the smooth smokes. This is where you make the next big step in quality if everything else is already dialed in. I recommend you mess around with it for couple of grown, lower N levels and nice fade in the end i mean, and I’m sure you will notice your buds smoking better.
..try it out for a while

How about some plant pics and we could further add insight?

Don't confuse things with common sense...........jeeeez.

This is the second time I grow this purple
Urkle
Pheno and it had shown a nanner at end of week 6, the first time grew it
I saw one end week 8

I grow in tents I had a small
Light leak in the back and one night I used the flashlight on my phone maybe it was that

However we have been having crazy fluctuations in temps and humidities 2 days each time I could not keep my vpd stable 1.2/3/4 at night during these days

Just how much stress is needed til they herm

Do you guys think it’s genetic ?

Same pheno that showed up first 2 times now

I also cleaned everything down first time with water
And bleach

It is Genetic & Environment, some genetics have a predisposition to hermie based on their preset hormonal profiles, as well when in flowering if those same plants get confused signals they end up, one of my f1's started making nanners at week 13 of flowering right after i accidentally gave it too much water, while the light hours where increassing, near the end of the plants life cycle in nature it is dieing slowly, if its dieing naturally and you give it water and nutrients its going to confuse the plant, "am i dieing?" "do i need to try and convert back to veg?" "should i try and make some seeds before i go?"

Why Cannabis Plants Hermaphrodite: A High-Amplitude Hormonal Model​

1. Hormonal Overlap Triggers Dual Sex Expression

• High Gibberellins (GA) promote male traits (elongation, apical growth).
• High Cytokinins (CK) support female traits (flower sites, nutrient flow).
• When both are elevated, plants can express both sexes—leading to hermaphroditism.

2. High-Amplitude Hormonal Fluctuations = More Herming

• Amplitude = strength of hormonal shifts over time.
• High-amplitude plants shift between male and female modes, increasing sexual plasticity and herm risk, especially under stress or transition phases.

3. Pollination Timing Alters Offspring Amplitude

• Top pollen x bottom pistils → creates high-amplitude offspring prone to herming.
• Top x top pollination → produces low-amplitude, stable-sex offspring.

4. Long Flowering = High Hormones = High Herm Risk

• Tropical landraces (Thai, Haze) flower for 16+ weeks.
• GA keeps growing, CK delays senescence—together, they prolong flowering and destabilize sexual commitment.
• Short-season indicas lock into sex early, reducing herm risk.

5. Evolutionary Survival Strategy

• Long-season landraces evolved hermaphroditism as a reproductive backup, keeping options open in extended, unpredictable climates.
