hey there Hansg, i get what you're trying to do i think , and it theoretically can and does work, but reason why it wont is because first of all the plant doesnt use exactly the same the molecules as we do, second, you're not sure of the dose, and there are ways around these issues, but it does cause problems more often than not. I use aloe verra (you can check my diaries for a recipe) straight from the leafs to make some kinda paste that can be used on humans as well as plants. Second and the most famous i guess is Molasses, you can always put a spoon in your coffee or in your yoghurt as well as for your plants. Then you've got milk and vinegar , lime juice that people sometimes add to the their plant for pH or as anti pest stuff. these last ones dont really work that well though. and the final wierd one i have for you is dish soap, humans dont eat it but we all have something like that at home. You add a few drops per L instead of a traditional additive with much the same results. Hope this helps ! 🚀
