To get the most out of your hydroponic system, it is a good idea
to monitor the pH and the strength (conductivity) of the nutrient solution. This is not
that important in gardens that don’t recycle the solution as most hydroponic nutrients mix
with tap water to a good pH and conductivity level. When recycling the solution, the pH
and conductivity of the solution will change as the plants feed from the solution. By
monitoring the pH and conductivity of the solution, and correcting it, you will get the
maximum performance from your system.

CORRECTING SOLUTION pH
Once you’ve determined the pH of your solution and find that it has
to be corrected, then an additive will be needed to make the appropriate changes.
pH Lower If the pH of your nutrient solution is too high then
some pH lower is required. Dilute some concentrate pH lower in some water and slowly add
to the solution, whilst stirring, until the desired pH is attained.
