So we have nutrient lockout due to low soil ph! 4.2 to exact.
Emptied the reservoir and filled with high pH water (7.5) and klorakleen to wash mineral salts of the root's. Left for 24hrs and emptied reservoir again and added nutrients back in and high pH water. Run for 3 days and soil ph is up to 5.6. Will run for another 2 days and get the soil ph to 6.5.
