Erster Grow ohne besondere Dünger usw.

If you using amendments in your soil like organic inputs such as blood meal or bone meals, these all take time to break down and become available to the plants. It's also good to note if you just transplanted with more fertilized soil it will take the plants time to establish themselves and explore the new soil and get all the nutrients out of it. Leaves kinda look a bit lime green to me in the pic, could be lacking some Ca Mg and maybe N The images could also be misleading me. Use this chart to help identify the issues. Don't forget PH plays a role in all this as well if PH is off then it can mimic deficiencies or toxicities. https://420life.com/wp-content/uploads/2021/10/Marijuana-Leaf-Deficiency-Chart-scaled.jpg I think if you have some liquid ready available nutrition on hand give them a bit of it, water aorund the root ball only not the whole plant and this will give it what it needs and allows time to go and get the rest from the other soil. On you next run I would suggest looking into adding perlite into the mix to add in some aeration to your soil as it can be compacted a lot and make it hard for the roots to grow. Good Luck!
