Tips turning color

Hi @gingilu it seems to me that it is due to the substrate being soaked, but nothing serious, these first leaves tend to yellow and fall. try to intervene more between waterings and let the substrate almost dry between waterings. try to control by the weight of the pots, the substrate when it is dry becomes very light and when it is very wet it becomes very heavy, try to orient yourself like this. good luck mate 👍🙏
