I recently started keeping track on my PPM input and output and have a question. I fill a 20 gallon trash can with about 18 gallons of water. I tested the PPM of just the water at 100 PPM. I then add my nutrients Jacks 321 and do 80% strength which gets me to 800 PPM. Two days ago I gave my plants a micro feed with Molasses, Seaweed, Tribus, and Recharge. I emptied my runoff tray, but there were still some dirt/debris in the trays and when I went to test my runoff water from todays watering it was showing about 1580 PPM. Is that because there was some debris in the trays still?
