Hi there Dieur, you're right the earthworm compost is too rich. You know it's a common mistake to think that just because you make it at home it's not so strong. It's very strong, you should always dilute it by 10x before you even add it. Live and learn, right now, i would suggest to start over. I know it's not what you want to hear but basically a plant with such stress at this stage will grow slower (stunted) and not produce enough. Sorry. Hope this helps ! 🚀
