Why have this plant decided to be droopy-doopy?

[Helmut79]

I mean.. all the other plants are fine compared to that. It looks like water stress, but how could it be? They have all been treated the same.

That particular one probably feeds slower or less. Most likely over watering. Or if you sprayed too strong of a neem solution or any oily substance. Causing the stomata to clog. Which results in droopy and / or clawed or curled leaves.

What type of medium you using? I have six plants I used 2 bags of ffof I get 3 plants out of each bag so I get 3 tall and perky ones and 3 short and droopy ones I'm thinking each bag of ffof is different

Put it where it gets the most light and I bet it comes around. I have a picky one going now that droops likes its dead when either it gets above 78F or the pot slightly dries out. After I water and/or get the temp down, bang it sprouts back to life within a few hours. Mine are quite a bit bigger than yours but it's interesting how fast the leaves will go from hanging down to arched up in full glory wanting light. This one is finicky but all signs point to a huge yielder.

Maybe soil is more compact, or drainage is blocked?

Is that 26c or 26% humidity?
If it's humidity,,,that's the key! To dry! The upwards cupping is an indication of heat/humidity stress. Keep heat around 68-74F and humidity to 40-50%

Hey Blaze,,,quit yelling!

This would be my guess as well, I have had it happen. Sometimes there is just a dense clump of soil/medium that holds too much water. Don't water that one as much and I bet it will come back quickly for you.

The drain can't be blocked, because I have used very fine coco in these pots. Although the seeds were originally planted in cubes which I transplanted into 2,3" cubes which I just recently planted into coco. Rock wool holds a lot of water in it though, but I've watered them as you would water coco - more often than you would water rock wool.

Might be that about half of the volume are taken by rock wool in these pots actually

The temp is around 24-28C and humidity around 50-70%, by the way...

Just interesting that it's the only one having these symptoms, but they were all given the same conditions.

Some of my few week old plants in perlite cups are doing the same thing. Not all of them are doing it though. I suspect it's the rockwool cubes I used to germinate the seeds(I don't use these anymore, this go was an experiment). For some reason certain one seams to hold a shit ton of water and take forever to dry out and the ones the healthy plants are in dry out fairly quickly.

 

[Helmut79]

I think you might be right about that.

The cupping is also a sign that the plant is try to transpire more and is having a hard time doing so. Heat/light to close are common causes.
