New Grower Help w/diagnosis?

[milkmann]

Hi all, need help! plants 21 days old now. Main concern is this plant which is almost hugging herself she looks so sad. Is this over/underwatering? In coco with a small amount of perlite mixed in. Started in 15L autopots, which I'm going to turn on soon probably, as heard many bad things about transplanting autos and had a bad experience with it last grow.. would this also explain the slower growth (the large pot/small plant)?

Environment is not ideal, running temps 26-29c ambient and 30-32c under the LED as experienced by the plants. Humidity is 35-45%. Small space (60x60x140) and trying to run 2 LEDs for 3 plants. (1x 240W and 1x 190W)

Had this problem for a couple of weeks now and I can't tell what it is, had lots of advice on here which I'm grateful for, but the problem still persists! I don't want to risk giving her a lot of water and worsening the problem. It's interesting to note that her growth has kept up with the other two in terms of leaf development and height, it's just the plant looks so damn unhappy...anybody got any ideas as to why?

After taking this picture I did give her 100ml or so of water and a small bottom-feed and will note if she looks any different in a few hours or in the morning. Still, would be great to get some opinions.

Cheers

This looks like either a PH problem or a nutrient issue.

This is a tough one,it could be a ph problem which would or could give you lockout. The bottom leaves look like it could be a ph fluctuation. I have never used cocoa but the only thing I do know is that it holds water longer. If you are thinking it is under watered be safe and don't keep giving it water to perk the leaves up just let it dry. I doubt you would have any root rot but it may be a thing to check,just throwing what little I know out there. The last thing you want to do is try and solving the dropping issue with water unless you know for sure it is under watered. I would imagine that with cocoa since it is a neutral medium you add you own from the get go.Did you give them the same amount of nutes with the same ph and did you test your ph through runoff? that is all I can help if it is at all. I hope you solve it soon because they do need some stabilization soon especially with auto's.

I say do a flush of clean bottled water and give the plant a few days and see of it starts to look better.
