extraction are typically reported as either parts per million (PPM) or milliequivalents (meq) per liter of extract. For other analyses most laboratories report results on a dry soil weight basis. PPM is commonly used, which is equivalent to mg/kg, a unit favored by some labs. Soil cation results may be reported either as PPM or meq/100g.

Ammonium-nitrogen concentrations of 2–10 ppm are typical. Soil NH 4-N levels above 10 ppm may occur in cold or extremely wet soils, when the soil contains fertilizer from a recent application when soil pH is fertilizationis not likely when the soil P is ≥ 36 ppm (72lb/acre) for row and forage crops, above 25 ppm (50lb/acre) for fruit crops and above 75 ppm (150 lb/acre)for vegetable production.Responses to potassiumfertilizationare not likely when the soil testsabove 175 ppm (350 lb/acre) for vegetables,row PPM (parts per million) refers to the concentration of minerals and soluble matter in your watering solution. Correct pH and PPM levels are the backbone of any grow room or grow tent. Making sure your plants' levels are balanced often means the difference between a healthy harvest and weak, unhealthy plants. Your runoff ppms sound high to me.

To convert from ppm to lb/ac, multiply ppm by two.
