Hey there Lukas, you see, the problem is that the plant is not static, it's always growing. When at the seedling stage, actually you dont need more than 50ml , then more and more as the plant grows , right? so the best is to respond to the plant directly, not follow a plan, that could lead to over or under watering. If it's your first time growing, try the lifting pot method to make sure you always get it right. Hope this helps ! 🚀
