i was led to believe that the truncheon was an all in one reader but does not mention ph is a ph reader needed as most tap water is neutreul
The Bluelab cF truncheon will measure the amount of nutrient in the solution, you also need to check the pH & adjust if required. Optimum pH for your nutrient solution is 6.2, but it is fine between 5.8 -6.8

when your ready to harvest and your flushing what should the reading be? and if i take a reading when im growing how will i know om giving it the correct amount of feed is there a chart or something telling you does it give you the reading on the truncheon?
The cF whilst flushing should be the same as your tap water, typically 2 in soft water areas, 8 in hard water areas. During the Growth cycle you can always refer to the chart in the back of our catalogue, but remember to check against your level of water hardness.
