This is generally true. When aquariums are unfortunately "blessed" with an
accumulation of nitrate, adding nitrate thru PMDD (or whatever) is not a
good idea. However, some aquariums (especially with few fish relative to
lots of plants) will not end up with an accumulation of nitrate and may in
fact be nitrogen limited. Only in such N limited aquariums,and only in N
limited systems, can there be a benefit from adding nitrate. 

As JP correctly says,

The key word is "blindly." Armed with an experienced green thumb or test
kits, however, many of the recipes can be applied with reasonable
confidence and predictable results.
