Flowering in spring. 6 weeks in but now revegging? Help!

mitchimal · Oct 19, 2025

Hey guys, have a massive issue. I had way too many clones sitting around so decided to chuck them outside. 10 on a coco perlite drip system, 4 in coco with a wicking gutter system.
For 6 weeks they've been flowering perfectly but in Australia our lights cycle has just hit 13h a day... Literally the week it hit 13h it looks like 2 of the strains have started revegging... They just started shooting everywhere! I swear to god I asked Gemini like 5 times what the light cycle would be in November and it was still under 13h but turns out Googles AI just sucks arse..
If it's not revegging what is it!? I'm 90% sure it is but what can I do now? I have way too many to put them inside under lights again.
I'm looking for any smart ideas please!
First thing I was going to do is top all the shoots to slow it down but if that's wrong please yell at me
Cheers guys

It is reveging, I wouldnt think 13hrs light would do that.
I had a clone I put out in early spring (march-april) when the days were around 13hrs still and it kept flowering for a while.
The buds will not mature any further - they are as good as they will get - unless you can get it under some artificial lights and back to flowering.
So, if you cant reflower - might as well harvest (if its anywhere near done)

Hey mate, so bit of an update. I didn't get time to try fix the issue for another few weeks but I've since made a tent to cover them overnight until 2 or so hours after first light to get back to 12 hours light. 1 pheno was already in it's late stage flowering and though it did start to push a few small shoots out of its clusters it's going to be fully finished in a week. The super lemon haze just looks like it never really got into flower so fingers crossed this works. My question is if it was to turn back into flower, will the existing flowers finish or will they just die off and the flowering cycle starts again or will it remember where it was up to?
Cheers

Depends on how much longer you wanna go I guess.
The bud tissue of the plant definitly has a lifespan - longer than a few months it starts to brown and die off. Also, all of the new veg growth happens in the stems - so any existing buds get all elongated and thin.
If you can get it under 12/12 itll turn back eventually(couple weeks) But (my experience) I think its probably given up on those previously formed buds already and theyre as good as theyll get.
My opinion - if it really looks like it just started flowering, and you can do 8 more weeks, go for it.
Itll (probably) be super leafy bud, many tiny shoots and little scraggly buds - but its something. At this point, faster than starting a new plant.

I just want to say regulating light on an outdoor grow completely sucks. Big lifesaver for me was a shed with a grow light in it. With flowering plants I set the timer for lights to come on in the morning so that it kicks on when they've reached the required amount of dark so I don't have to scramble out there at the exact time to take them out. When I'm vegging I have them come on in the middle of the night and they stay on until I go pull the plants out in the morning, whenever I feel like getting around to it. Because stuff like leaving your house to do shopping or going and visiting friends and all other activities would require you to be around to do what has to be done at the right time. And that really sucks.

Yeah I know... I didn't have the experience to realise this could happen. I just thought, if they're used to 18h which they were for 5 weeks they will think anything less is flower time... I did however ask Google about how much light there will be when I thought they'd be ready and it gave me the wrong result so I'm half to blame lol. 6 of these can be moved as there just in a drip but the big 4 are in a passive gutter wicking system so can't easily be moved when I want to... I just need them to bloody finish! I won't grow ultra haze 1 again.. it takes like 4 weeks of 12/12 to even show flower sites I might just have to leave those 4 to flower over summer (here in Aus) so April/may harvest. They will be monsters if they veg that long. Could probably do 3 auto crops below they finish

I learned that lesson... sudden change from 20 hours down to 14 hour day will likely trigger flowering but also likely won't stay there with insufficient darkness rest (under 10 hours).

Flowering in spring. 6 weeks in but now revegging? Help!
