good mornimg everyone. I'm unable to determine what my issue is right now. I recently added in about 10-15ml of potassium silicate into the mixture, as well as 1/16 of a cup of zeolite (calcium feldspar), almost immediately the plants started showing signs of stress. I pour in 2 cups - 1L of water almost everyday. The remedy is to back off on watering them, and flush them out completely. Are they being overwatered, or is this the result of nutrient toxicity?
