Something’s wrong; they may not be salvageable at this point. It’s not clear if you started seeds but it sounds like it. If so, you are probably not going to get anything. B-sprouts are best started indoors, well in advance of the growing season (see above). They are heavy feeders that demand rich, fertile soil—the more aged manure, the better, and compost—but usually from the beginning, when seedlings are set out. Before you go to any trouble, you might want to check the soil pH. B-sprouts need soil to have a moderate pH; 6 to 7 is good. It can take a season or so to change that so check it first. Finally, when or if b-sprouts appear, know that they can benefit from nitrogen, but not to excess.
