@@Fingers,
Howdy. Sorry for a delayed response. It has been busy around here lately. I measured what was there which had been sitting around. It was 761 ppm and 5.68 pH. Measuring after the next watering was @ 1k ppm and 5.46 pH. I may go ahead and flush next time. They are looking good and I am not seeing signs of any problem, but it would be good to avoid any issues. Would you flush with just plain pH'd water until runoff is back to what is going in?
