Hi
@ScoobySnacks77 You must change the cycle of light hours to 18/6, it will grow better and faster. the distance from the lamp seems fine. it only begins to give vegetative growth fertilizers after the second real pair of leaves is born to form well. your substrate seems to be soaking wet. the roots need oxygen to develop, let the substrate dry well between each watering, control this by the weight of the pot, the substrate when it is dry becomes very light and when it is very wet it becomes very heavy. good luck mate 👍
