I don't understand this

Hi Ina,
ppm means parts per million...  I personally don't like intensive
fertilizing strategies, too hard with a plant that flourishes in our
conditions anyway, many people get it slightly wrong because, such a
recommended dose rate often fails to consider environmental
circumstances.... Temperature, rainfall, soil acidity etc, so for example
if you & someone in California & my self all used the same dose rate we
would all have a different growth rate result.... With some species, you
would also have to consider, that they may need seasonal fluctuations in
mineral uptake to spark the flowering cycles.. Sometimes you may achieve a
wonderful growth rate, by stringent fertilizing, but may sometimes reduce
flowering rates too.....
If you use the analogy of hydroponics, there you see plants growing at
optimum rates but only if the chemicals are carefully measured to the ppm,
even small fluctuations in chemical rates can be detrimental to the plants
& crops can be quickly lost through under or over feeding over very short
time periods.....

Hope that helps Ina
