Hello mate, you might have different couses, starting with genetic ending with mistakes from you. I see from your diary that you have 23°C with 75% RH, you have the correct RH but for an highter temperature like 25-27°Cto give the right VPD for this stage. I think also you have you led dim at 100% now, even if you put it at 70cm of distance the intensity of the light is too high for this stage, try the 50% at the same hight. You give they a solution with pH 7 that is too high, try to keep it around the 6.2. Also until the first/second week of vegetation a prefertilized soil is enough so don't feed they if not with only water. Now you sould let rest your little ladies until you'll see normal leaves come out then you can think to train and to feed them. Good luck and happy journey!

Hey mate, is that tent the whole area? Then you can stick to 4 plants anyways and train them a bit, will be a way better outcome than mainlining single onestemed plants, they shaped different an will overcultivate the area. Just top them after the 3. Node and let them grow :)

Definitely need a chill pill. The malformed ones are probably just outcomes of heavily inbred plants. One or two look like they might have received too much light too early (nodes a bit too tight). the first 24 hours they are a bit more sensitive in that regard. Relax. seedlings can look funky and turn out perfectly fine. watering is simple 1) saturate entirety (if soiless go beyond with a minimum 10% runoff and fertilizer every irrigation) 2) wait for top to dry and repeat - this varies by how the substrate is constituted. up to 1" deep in a soil-like context of high water capacity and insomething like coco when the top layer changes color. if you are deviating from that you are objectively doing it wrong. don't over think it and don't randomly choose how much water you give because it's a round number, lol. use smaller pots for seedlings. in this context of a big pot/small plant you may want to only water a diameter of substrate slightly wider than the leaves, but do ensure it gets saturated all the way down to the bottom or you are just training the roots to grow poorly or causing dry pockets around roots etc... you want roots driving down, not growing upward seeking moisture.

some look ok. some look sad, give em time like the others have said.

75RH%

I'm with asnoriu on this one. Let them be and see what they do.

Leave them alone for one week. They will bounce back. From soil look - its well moisturized, will last those 7 days easy. I could show you million of my grows were something was not happening, all still ended up normally. Stalked them, but dont touch them. Make sure you have good humidity and small air movement. Direct wind or even strong oscillating can cause damage too .
