Your mention of Liquid Nettle Manure is the first Iโd heard of this. I was curious and researched the NIH study on its use growing potatoes in Spain. I read the long, boring article to get to this conclusion;
โNettle slurry foliar fertilizer treatments (including Urtica combined with Equisetum) did not have any effect on yield, chlorophyll content or the presence of pest and diseases...โ
Sorry to bubble burst, but you have a right to know. Hereโs the full link to the study
