twisted leaves

Hey gardener! It's because your soil is loaded with nutrients, so your little plants are shocked and have the first leaves that are deformed, but as you can see, generally the leaves that grow afterward return to their classic shape. It's just a reaction to the nutrients; you'll see that if you plant everything in less fertilized soil, you'll be able to see the leaves grow normally. Good luck, bella ciao!

Too much high PH for Coco, thats mean that you can't reach perfectly all the nutrients, ideal is sweet spot through 5.5 - 5.9 also, this def is tipically from calcium then you need to add calmag here even to reach saturation of Coco medium

I’m not an expert - so see if you can wait for a second opinion. For me my plants twist and turn when they’re heat stressed or too close to the light. I had some really bad leaves myself in week 2, but after moving up the lights a bit and giving them some time to grow, they straightened out again.
