Are custom fertilizers better than the general stuff?
Not unless you overdo it. It has more nitrogen than some plants need
and can burn if you use too much. But unless you have a serious
deficiency of P or K it works fine in moderation. Folks use to use 5
-10-10 and sidedress nitrogen loving plants like corn and brasssicas
with nitrate of soda. Most folks today use 10-10-10 which why its so
readily available.
