If you see any signs of over-fertlization, you should immediately flush out your growing medium to allow the plant to recover before further damage is done. Use only clean water until the plant shows symptoms of nutrient deficiency. Then you may resume your normal feeding schedule.
Depending on your hydroponic system, flushing may require top down watering to completely clean out the medium.Another good time to do a complete flush of the plant and medium is around 2 weeks before your expected harvest date. That will help prevent the vegetables from tasting like your hydroponic nutrient solution.
