How many add trace elements on top of hydroponic nutrients?
I have just been doing some research on trace elements needed by plants. My hydroponics fertilizer contains all of the 11 traditional trace elements except for tin, cobalt, and iodine. How would these affect plant growth? I am getting decent yields and am not that conserned but I always want to do stuff the best way possible. If you use trace element additives what results did you see?
On a side note I wonder if adding a multivitamin to hydroponics would benefit the plants in any way? Has anyone ever tried this?
