Maybe, do you know what is in your water supply? It can vary
quite a bit - you should be able to get a breakdown from your
local water district.  Some are even online.

For example, my water is very low in most dissolved salts of any
kind, 40 ppm max.  I have to supplement just about everything:
K+, Ca++, Mg++, NO3-, B, Fe, etc etc etc.

There are ways to know if your plants are suffering from
a deficiency based on how the leaves are affected. Chuck
