if ur in soil u won't need anything yet, i start nuting after the 10th day, once a week with fish emulsion (5-1-1) first, then i keep the fish goin once a week and after the 2nd or 3rd week of veg i add foxfarms grow big (1/4 recomended)(6-4-4) once a week, and once i get into flower i'll do bat guano tea once a week (4-6-2) and 3rd week into flower i'll add on foxfarms tiger bloom(2-8-4) once a week along with the guano, and one or two weeks before u harvest water with only fresh water and i use a flushing agent as well (flora clean) but its all dependent on what ur using, because what works for some may not work for others
