Hey ICMAG!!!!

I am growing in rockwool. Started from seed in rockwool starter cubes.

Once they showed quite a few roots, they were transplanted into 6"x6" hugo blocks. These blocks were soaked for 24 hours prior to transplant in PHed 5.5 water and then let drain before transplant.

MY ISSUE:
The day I transplanted, every single seed was in perfect health. Nice and green and perky.

Since the transplant, the leaves have started to curl up underneath themselves as pictured below.

WHAT SHOULD I DO?

I'd wait for someone more experienced to answer but is it not just over watered making them droopy and maybe you should just do nothing for now?

They were transplanted 4 days ago. They haven't gotten any better but I wouldn't say that they've gotten any worse either. Growth doesn't seem to be slowed much.

Do you have air circulation or fan positioned to blow over plant to create
breathing for them??

They look like overwatered plants,its no issue but you sound like worried owner
of his very best pets.. its a good thing as plants feel love and they will give it back..

aircirculation could raise their leafs as this is how plants breath in nature... and if they are overwatered they usually put leafes in that position,give them more air movement
and then watch does anything changing..

They are in a 4x4 tent with 2 6" fans inside as well as a 6" exhaust fan and 2 passive intake holes at the bottom of the tent. At first I thought transplant shock and also overwatering but it's been 4 days since they were transplanted and nothing has changed. Tops of the rockwool cubes are pretty dry and they aren't by and means light, but they aren't nearly as heavy as a freshly watered cube. I don't want to water them again if they are overwatered but I think what may have happened is that the bottom 6" rockwool cube wicked all of the water out of the 1.5" insert cube before it had time to root into the bottom cube and therefore left the top cube bone dry and not yet fully connected with the bottom cube with all the water.

Any thoughts?

Wait and look,its a good thing there is no yellowing and they grow further..

They aren't necessarily yellowing but definitely not all are a lush green. More light green. They haven't had anything but minimal water and an occasional mist since transplant 5 days ago. Hugo blocks as getting pretty light

i think maybe you could have killed some root developement or they are fighting off damping off maybe ?

(re: uneven moisture of substrate)

-----------------

if the cotleydons are yellowing first, prior to the leaves, then maybe they are short on some nutrient ? OR they are using nutrient to re/develop roots

----------------

it does like overwatering though (?),

looks like the roots are lacking air/too much water, this might be whats happening
rock wool can retain a lot of water, enuff to limit air to a smaller plants root system.
a 30min soak does just fine,
after that I get excess water out by slinging the cube like your throwing a baseball,
I do it in a downwards motion to sling excess water
into a 5gal bucket.
BUT--->very important!!---> you do not want to the hold cube so tight as to crush the rockwool.

this may or may not be whats happening but if everything with your gro conditions are the same before and after transplanting
I'll put my money roots are too wet/ not enuff air

goodluck :tiphat:

The bigger rockwool cubes as well as the smaller starter cubes are pretty dry. Even the bottom of the rockwool is almost entirely dry. Everything is still growing. The first set of true leaves are still curled and some of the new growth is starting to curl as well. I agree that it was probably overwatering from the initial soak and flush of the Hugo rockwool cubes prior to transplant. However, it's been a week since transplant and the cubes are dry as mentioned above. I haven't seen any improvement in the perkiness of the leaves but as mentioned as well, there is new growth happening. They definitely aren't dying. They just need some love. Problem is, I'm not sure what needs to be done to nurse them back to full health. I've just been watching them but I would imagine that they'd need some nutrients by this stage of their life. They have only had the initial flush of their larger rockwool cubes with 1/2 strength nutes a week ago at transplant. Other than that, it's just been light misting and 1 top feed with plain PHed 5.5 water a couple of days ago when the cubes initially dried out. Now they are dry again.
How can I supply oxygen to the roots if they have yet to come out of the larger rockwool cube?
RH is around 30-33% during the day and 40-50% at night. Temps are pretty steady from 73-79. Normally around 77 during the day and 73 at night.

I have seen this problem. If you stack rock wool then you would know how rock wool has a wicking effect. Basically the coco is sucking the water out of the rock wool. Next time get rapid rooters.

Yeah I mentioned that above. I figured that the bigger rockwool cube was sucking all the water out of starter rockwool cube prior to the roots fully locking into the larger cube. That is why I've been top feeding.

I'll definitely give rapid rooters a shot next time, but what do you recommend in the meantime to help this batch?

we've tld you how to fix it already but you wont listen. the cubes have not dried out yet or else you would be posting and telling us that they are getting better. when the roots start to get air again they will start to grow out and the leaves will start growing new tips again. if none of that is happening it's because either it's too far gone, or the block is still wet. if it was fully dried out beyond just being lightly moist/damp the plant would have dried up, wilted over and died.

like I said, like multiple people said. let the shit dry out and it will recover on it's own. a 6 inch block of rockwool is
A.) huge for starting a seed.
B.)holds a lot more water than you think.

I won't listen? I have done everything that everyone has suggested that I do. I said that there is new growth. Plenty of it. I've let them dry out. I have not denied anyone's advice. I have just not seen any progression in the initial leaf curling in a week. Some of the new growth is curling as well. I plan on letting them dry out further as I have already been doing. I'm just open to any other advice people may have.

Also, I didn't start the seed in a 6" block. They were started in 1.5" starter cubes and transplanted into the 6" cubes once roots were coming thick out of the starter cubes. Maybe if you had read some of the other comments, you wouldn't be so off base yourself.

well first off. the leaves aren't gonna uncurl. so if that's what you're waiting on you're watching for the wrong signs.

secondly those seedlings are what? a week maybe 2 weeks old when you put them in those 6" cubes?

for comparison this is a 3 week old seedling in a 4 inch pot.

this is about 3 weeks later when I put it in a 6" pot.

you essentially started off a seedling in a 6" block of rockwool. it's currently waterlogged and I hope you can recover it.

:tiphat:

Ok for future reference, should I start the seeds/clones in 4" blocks and then transplant to 6" blocks?

you should leave them in the 2inch starter cube till they are almost as big as the plant in the first pic. the leaves collect the light to feed the plant to make it grow. the roots find the water and the minerals to send to the leaves to make the food.

your seedling was too small when you transplanted. now it has an abundance of water at hand, no need to grow roots. since the leaves are small it doesn't have much food at hand to get taller and grow bigger leaves. it can't grow bigger leaves without bigger roots, but it can't grow bigger roots till there's a need to go looking for water.

as above so below.
