what is going on in flower??

[zachrockbadenof]

That's not foxtailing, guy.

He's running cmh lighting, so that can't happen. If it isn't a timer issue, then it has to be a hormone issue. I'd be curious what kind of supplements are used here. What is the soil, did he mix it himself? Superthrive, or anything like that being used? Lots of stuff out there that can fuck with hormonal responses.

If the timer is ruled out as the issue, I think that's the only remaining possibility.

soil mix 50pct fox farm ocean, 40pct promix, 5pct castings and the balance perlite... i use fox farm nutes, always diluting em a bit under the recommended level .. since i have noticed the hiccup, i have not feed them... i'm at 55 odd days, so i figure there is enough nutes in the soil...

hey.... the sdkush is from rez, 15+yrs ago... the somango is from soma 20yrs ago and the geadbanger is from karma 5-7yrs ago...

yesterday the lights went off at 5pm, b4 bed at 1030ish, i checked the room at least 1/2 dozen times, and then again around 3am and then at 6am... no light on...
with cmh's i believe its light on or off... there is no inbetween...

since the lower buds appear to be fine, would it make sense to chop the tops and concentrate the light on the lower buds??

One of the more interesting situations I have seen described. I look forward to seeing the continued responses, no shortage of sharp cookies here.

Sure looks like a classic reveg.

If you're using one of those digital timers that has like 8 different on/off settings make sure that one isn't randomly set. I'd reset the timer to default and reprogram if you're using a digital timer.

There are also signs of overfeeding on those leaves. If you overfeed and use a bunch of additives you can have issues that could manifest themselves in that fashion.

Yeah, I really don't even worry about light leaks. I never get hermies, I think "breeders" use that as a convenient cop out excuse to cover for their shoddy work.

My outdoor grow is beside a dusk to dawn yard light on a pole and no hermies and flowered fine but I have forgotten to turn the ceiling light off indoor and they stayed in limbo. Another thing I am not afraid of is turning the lights briefly on or using a flashlight during a dark cycle if I have to , I have done it many times and no hermans.

 

[Dime]

I also have humidifier,heater,dehumidifier,power bars and they all have small lights on them. If it's part of the grow from the start they seem to ignore it,just like the yard light and the full moon on a clear night . I agree with Wolverine that the hermie trait is genetic. In the old days we would intentionally stress plants to find hermies to ensure stability.

Weird, it does have that classic single leave reveg look.

Yeah it's 100% revegging, no doubt about that.

That only the tops are growing but the lower buds look kinda normal is also expected behaviour. I don't know any hormonal treatment that interrupts flowering? It has to he light pollution.

Get a smart socket. You can use them as timers but that's not their best feature. They have energy consumption measurement and logging. Then you can see if the lights were off (and power was 0) or if there's something weird going on.

One example would be interrupting florigen production. There are probably several ways that could happen. Gibberilins, maybe even triacontantol (sp). That's why I was asking about any supplements, and what specifically is in his soil. Too much Superthrive could do that... as one example.

But I agree that light is/was the most likely option, that's why I said check the timer, first. But I highly doubt a small light leak is going to do that... maybe, but I doubt it.

What kind of lunatic would use gibberilins on cannabis?!
I've never read about any effect triacontanol has on flowering. Do you have a reference handy?

Why is this in the hydro section then?

 

[FletchF.Fletch]

Is the light cycle being run to coincide with with actual daylight? Or are the lights on when it is actually nighttime outside?

Also could be due to a fertilizer correction. If they had been getting too much, and then are flushed and corrected, healthy budding growth can begin anew. Especially with certain strains.

I was responding to your previous comment, that you weren't aware of any hormone treatment that would interrupt flowering. I listed a couple possibilities. But no, I'm not going to go hunt down links.

Triacontanol reduces mid flower nanners from what I’ve seen.

Some of the best strains and cuts in the world put out nanners with any stress at all. It’s one of the traits that can make growing top shelf cannabis difficult.

Since this is a cannabis forum and a thread about aborted flowering without application of unusual PGRs I think my comment is warranted.
Regarding your unwillingless "to go hunt links down" I just remind you that extraordinary claims require extraordinary evidence. Triacontanol is associated with earlier flowering in different species. I have never seen it associated with delayed or interrupted flowering.

Context matters

People use kelp extracts. Kelp has gibberellins.

Also some people really like to argue. Think I'm out of this one.
