Plant suddenly extremely droopy before and after watering

[Kazooey59]

Hey guys,

So I'm currently running my last autoflower in Biobizz substrate. It was 100% fine until 3 days ago. I recently ordered a new bigger LED, and after I opened the tent to install it, I noticed that my autoflower is SEVERELY droopy. The pot was light, not dangerously light, but light enough to get watered again, which confused me. I then watered as usual, in hopes of her just being underwatered. 24 hours later, and it still looked like this. 48 hours later, and it actually worsened in some way.

Here are some details:

1. Biobizz All Mix in final pot, two transplants with Light Mix. 100% healthy all the time, last transplant was around 15 days ago.
2. Dutch Passion Daiquiri Lime Auto, 36 days old, still not flowering, but it had shown the first tiny pistils (sexing on the stems) around day 31. Topped, LST.
3. 14L Airpot
4. MarsHydro FC6500 EVO @ only 300PPFD for now, measured with a physical PAR / PPFD reader, lowered from 500 to 300 in case of light stress. FC6500 should be running on 75% by now, but it's only at 30% to be safe.
5. Tapwater, 3-3.5L of water at every watering with minimal runoff, around 5% maybe. Wet / Almost dry method, going by pot weight, worked flawlessly
6. Biobizz Grow, Algamic, Heaven, and Activera, water sitting at 6.3-6.5PH before watering
7. Exhaust running, fans running, everything works as needed
8. Temp / Humidity not picture perfect, but my plant was 100% healthy until 3 days ago. Around 23-24°C, 55-65% humidity, 24/0 cycle

Any ideas as to what the hell is happening here? I've done literally nothing, I thought about every detail so far. No foliars, no weird additions, nothing. I'm totally clueless and insanely worried about this plant.

Please help!

Hello ^_^

Are the leaves really droopy when the pot is very very light, and then get droopy again after the pot is very very heavy?

Sounds quite like droopyness (often caused by underwatering and also often cuased by over watering - quite the conumdrum eh!)
You could check that the pot isnt sat in run off water after watering.

Autos don't really like transplanting. For next time, i'd bypass that all mix completely - go straight in with the light mix in its final pot, give it 20 days to establish and then start trickling in (and buiilding up) the nutrients it needs.


Hope this helps ^_^

edit: - you could also try dropping the 24 hour light to 18hours or 20hours - sometimes they just need a rest

Hey Blue!

The plant was absolutely happy until a few days ago. No droopy leaves, nothing. It grew like crazy, it was an absolute beast and a workhorse needing a few defoliations here and there, which is why the leaves currently also look a bit tiny. The pot is standing on a pot raiser, it's just hardly visible as it's an airpot, but there's a raiser on the bottom, keeping the pot away from any runoff water or contact to the slightly cold floor.

This droop came out of nowhere, as I've never in my life over- or underwatered a plant this severely. The transplant never shocked them in any way, as I usually let the next pot "warm up" in the tent for 24 hours, and use great white or dynomyco to avoid most problems. They usually keep growing absolutely fine after my transplant, this one too. It went from Light Mix in the beginner pots to All mix in the final 14L pot.

This is the same plant just a few days ago. Looks absolutely fine, a healthy green, nothing out the ordinary



I also changed the cycle to 20/4 yesterday, but as of today, it looks worse and worse, literally like it's dying

I'm leaning towards transplant shock then.

I've found both Biobizz soils to be reliable over the many years i've used them (although i don't transplant and stopped using allmix once i'd changed over to lightmix) - which kind of rules out the soil PH (although you should probably check it if you've got a soil probe to be sure and tick it off the list)

There aren't that many possibilities when it comes to droppiness.

This was my plant post transplant (old image), already in heavy LST mode, it was long ago. Do you think transplant shock will suddenly appear after 2 weeks of being transplanted? Might have worded it incorrectly, but the last transplant was long ago. It was 100% healthy until 3 days ago, loooong after the transplant. It just drooped out of nowhere now, and it gets worse

It doesnt look that bad. I'd keep the light to 20 hours.
No - trasnplant shock doesnt usually happen 2 weeks after transplanting (from what i've seen over the years - but not a transplanter myself)
