Hi
@Haggiz! You have two problems coming from the same source. First problem: leaves are yellow. Second problem: leaves are droopy. Source of the problems: too small container. Indeed, your rootmass is not able to look for nutrients in the soil, since it's very small. Plus, you were very light on your feedings, with only 1-2 ml/L of BioGrow, this was probably not enough for a 3 weeks old plant. Now about the droopy leaves, it's related to your small pot because your rootmass cannot retain water/humidity for more than a few hours, a 5L pot full of soil is not able to host a lot of water anyway. You should transplant that baby into a bigger container (AirPot/SmartPot..at least 11L/3gal) with fresh medium, and water immediately once it's in place. Water until you see a runoff coming from the bottom of the pot. Then let the medium dry a bit before doing anything, see how the plant reacts. Hope this will help, let me know in the comments section if you need any further information, and happy growing! 👊
