The 1:5 soil/water solution was mixed on Friday, but we did not test the solution until Tuesday. No significant color variation from the reference samples were noted in any of the tests. Did the solution set too long? It was in the barn - does a temperature of 45 to 50 degrees affect the results?
The Luster Leaf Rapitest Soil Test Kit 1601 has specific instructions listed here for use for testing and results. If it has been 5 days, you will want to perform a new test as directed.
