I just got some new plants Ludwigia palustris, limnophilia hipporoides, and s. repens. How much ferts would you add per day to keep especially the Ludwigia palustris healthy and red? I don’t use co2 and do a 50% water change every week. The fert I use is Nilocg thrive all in one that has 2.56% nitrogen, .42% iron and other micro and macro nutrients. I also use uns controsoil that is 8 months old. I recently added seachem flourish root tabs to it. Thank you for any help!
