Rapitest Soil test kit

[nnjjohn]

Okay good people, I'm not sure what is going on here, hoping to get some good advice before rather closer to planting these beds in mid May here in northern new jersey. The test kit always indicated depleted nitrogen.. potash (k) always looked on the high level level or (surplus) P- Potassium always looked suffient or high (surplus) if I leave the P test kit over night the color gets dark..so the result is a surplus of potassium I guess. Funny thing about the ph though was a month ago, all four tests in all beds tested second color sufficient or the darkest of the green which is surplus of ph.. yet this is my most recent test results.. notice the ph is actually blue!!!! anybody know what blue might indicate? tia, john
