What is the conversion rate from growmore to plant matter?

Yes, I already know that there is no such thing as that but ..., in an
ideal situation for each gram on growmore how much plant matter will be
produced? - assuming that no other nutrients are limiting. I want to
know the theoretical maximum.

I use growmore on my garden vegetables and I usually put it around each
plant, half a teaspoonful at a time.

So, for instance, what is the most growmore I should give each
individual parsnip or strawberry plant?

Resh, arguably the bible for hydroponics, estimates that all the elements
other than hydrogen, carbon, and oxygen (primarily from water and carbon
dioxide) is approximately 1.5% of the plant's weight.

GrowMore, makes a number of different formulations so you would have to be
more specific. Any calculation is complicated because the formula on the
container is not given in terms of elemental composition. For example, the
phosphorous is defined in terms of the equivalent of what is called
phosphorous pentoxide (P2O5). Moreover, any fertilizer will lose
functionality when one of the constituents runs out.
