some one please explain to me how to nute a plant, and i mean like testing the run off then what do you do from there??? how do you know when to add more base nutes? do you add base nutes and supplements at different times? i haven't every seen anything on this maybe thats why the main problem is over ferting and not flushing right.. sounds funny but its true i bet some one needs to make a post pertaining this. also whats the diff between bigger percents vs lower just the percentage lol? time release i assume.
