Nutrient lockout
In soil, the salt and PH can build up, in this case, flush the plant to clear the soil/growing medium from excessive salts
Flush with PH adjusted water until the point that runoff is similar in PH, after allowing the soil to dry to prevent rot roots and then start watering with the fresh mixture
And add more calmag to the fresh mixture
