blood meal?

so does anyone know if Lilly Miller, Natural Formula, Blood Meal, 12-0-0 is good and how much do i use? I just had some of my plants come out of the dirt today they are only like 1 week old and came from seeds

thanks

i say that NPK isnt good your plants need more then just nitrogen when vegging id go for a 3 part veg solution like 10/4/7 example. and dont feed your plant yet u will fry them , your soil has nutes in it allready wait atleast 2 weeks , imo 3 weeks tho
