This got my attention as well.


I learned long ago that the advice of distant strangers(or anyone really) should be no more than a guide, not a gospel, and to always verify things for myself.

Anyway, let's just apply logic: only one thing was changed in the grow space per the information you provided(green light), problems quickly arose. What does this suggest your first action should be?

(not trying to sound rude, again, just trying to apply logic to the facts given)

If removing the new light doesn't help, seek other causes, but that first step seems clear.

Devastated. Finding nanners in ALL the ladies. The worst part is I can’t understand why??

what could possibly explain a room with 5 strains all throwing nanners at the same time

i’m sure there are no light leaks as I checked when room set up and again this morning (there was a new green led for the last week but it’s relatively dim and I feel confident based on comments of others it should be an issue)

for example even if ph was off, or whatever like it doesn’t make sense that every single plant would throw nanners??? I’ve been feeding them at 5.8 600-900ppm nothing crazy and I let 20% runoff. You can see from previous photos that they look mostly health. The nugs are stacking!!

so what the fuck. I could live with it if I at least knew what to fix.

maybe heat and light stress as I have a lot of light in there but mostly they’ve looked happy and again how would they all herm??

this is how the room was looking. Yes a few plants (close foreground on left) have some issues zooming in but overall the majority look happy no?

Is the green led on all night and what purpose does it serve? If there isn’t something you need to do with lights off I’d get rid of that
 
I am also wondering as I have a few testers of wedding crush and candyland crush currently running. Cannabis does photosynthesize in green light and if left on that may well have been the cause here.

No offense taken. Coincidentally it was yesterday I had decided to do a random light leak check before lights on (my stem rubs that resulted in finding the nanners wasn’t till later). Of course as soon as I saw the green led glow I fixed it.

But i’ve since heard from respectable folk here and in person that green leds on their equipment has never been a problem.
But back to your good point - where does logic point to?

It must be something that affected the whole room in a big way.

Co2 was added at 1200ppm with a 400 dead and a week ago the same day the led was added so the stress of co2 and the led are suspect.

I had been monitoring the co2 for two days (I have a thread about it elsewhere on RIU) before adding co2 and it was already 800 when out of room and over 1200 when I was working in there. So it’s possible the tanked co2 added stress but I don’t consider it highly probable. Same goes for the related led. Possible but unconvincing. (Side possibility - perhaps green LEDs aren’t issues for other growers when the leds are there from day 1 but that was not true in my case)

They are all getting the same food is another possible environmental stress if I messed that up. As per prior comments while the feed surely hadn’t been perfect the plants are far from looking globally unhealthy.

So where does logic lead me then lol.

I went through them all closely today;

Gelato were least affected. I kept 6/6. A few I couldn’t find nanners and the others had only one or two places small and under bottoms which I sprayed and removed.

unfortunately the Wedding Cake and Pink were both worse. The gelato I really had to look for them but the WC and P they were more prevalent. I killed all the pink (7/7) and kept 3/6 wedding cake. I killed Strawberry (1/1). Going to keep watching them daily and decide whether I go another 5 weeks. I still have clones of everything.

(I read the above but saw no reference to green light causing hermaphrodism)

My understanding is plenty of growers use lamps like these when they need to be in the garden at night AND they swear no issues with hermies etc.

the single co2 monitor led was much less bright than one of these headlamps even on the lowest setting

as I said before if I were to continue this line of reasoning then maybe it’s not the green led alone but that it came in from nowhere at week 3. Not convinced this is the problem but can’t rule out.
 
(I read the above but saw no reference to green light causing hermaphrodism)

It is not that green light causes hermies its that any light that the plant can photosynthesize under that can cause hermies during the dark period. Cannabis photosynthesizes under green light and in my opinion the green led is seen as a light leak to the plants.

Understood.

But you don’t address how growers the world round have been getting away with using green lights during the dark without stressing the plants.

so not disagreeing with what your paper says but anecdotal evidence cannot be ignored.it’s hard to reconcile the two.

I do not disagree with you here but the research shows they use the green light so I would suggest they were stressing the plans somewhat using the green light. Duration and intensity must play a role as well here. I would be curious to see them re ran again under the same conditions without the green led in play.

With all the fucken power shortages here, I was glad I even got some females so I know these gals are solid ones. Looking into buying some of the Blue lines since those are already tested. What sativa strain can you guys recommend?

Black Candyland is fucking awesome.

I feel like genetics are a huge factor here as well tho, no? For example, I've got plants that I revegged under 24 hour light in a +100°F tent. I have 7 diff strains / phenos in that tent, two of which were herm offspring. One of the herm offspring nannered it's ass off, like literally as many nanners as pistils. The other of the two herm offspring didn't herm under 24 hour light and 100+ temps. So ya, 1/7 hermed for me in those conditions and it was a herm offspring and the other herm offspring didn't herm.

Yes I agree genetics play a huge role as the father of these plants was all the same and it is possible that has a huge influence here, time will tell as others run the seeds. I too will find hermies in the seed run and then in clone I may not see them hermie again and others carry on with the trait, usually around week three of flower as the girls hormonally swing into flower in full swing. I too was thinking it is both likely to do with the genetics and the green lights influence together causing hermies perhaps in Hot Boxes case here.

yes to a degree I also have to doubt the genetics i’m using particularly that they all have the same male.

I’m not ready to trash the genetics but it’s definitely a non zero possibility they are at least involved (ie weak genetics would be more prone to failure under any kind of stress)

a few experienced folks have pointed to genetics as suspect in light of all details. ‍bongsmilie
 
If you google a problem you can always find something to confirm so I take this with lots of Epsom salts but this thread talks about God bud being herm prone (Look for April post by Guest). Of course the original blueberry was also known to herm.

please note I never pointed my original aims at trashing genetics but I think the community benefits from honest discourse. I’ll assume this was user error for now. I’m checking the remaining 11 daily.

Yea no doubt, and tbh, if there was a strain that's really awesome but it's a princess that's kind of just life. If you like that strain and it herms when you don't treat it right, just learn to treat it right. I'm sure you guys have heard about the speculation that OG came from a herm.

I agree something mass environmental (and prolonged?? so get almost every plant affected) is probable.
But I've been very careful about light leaks before a plant when in and checking since. I have max min thermometers that rule out any mass heat event. I use EC/PH meters which I actually maintain. I'm going over everything and it just doesn't add up. The plants are mostly stacking save for maybe 4 of the bunch that have visible issues.

I encountered a similar situation a while ago, it turned out to be a space heater that switched on only at night cycle had a red light that was only visible when it turned on.... If any space bars or plug ends light up when powered, and are only powered at night cycle? I took a peak a few times during a night cycle and let my eyes get dark adjusted. The plants beside the light source were most affected, that may lend some clues if the problem is worse in one area of the grow. Hope you figure it out! When it all clicks growing is magic... when it doesn't it can be an exercise in insanity
 
Anyone know why JOTI'S instagram page has been removed and a lot of his gear is out of stock now... Hope everything is still good
