After the initial germination phase and the development of the first leaves, I began feeding the plants with a nutrient solution (fertilizer) after about 7 days. Currently, there are no noticeable issues. The plants are receiving a light intensity of approximately 400 PPFD.
@TherealNICOGREEN, Bro, I’m really sorry, unfortunately, I don’t speak Danish; I always translate it with ChatGPT. No, I made the name tags myself with my 3D printer 😊
