Hello. I recently purchased some Fe-EDDHA 6%.

I prepared the nutrient solution with 0.9 grams of Fe-EDDHA in 100 ml of distilled water. From this solution I took 18 ml to dissolve in one gallon of water to obtain about 2.57 ppm of Iron.

The color of the solution is dark red, like Lipton Tea.

I tried using only 0.7 ppm and the solution is still very dark.

Has anybody use Fe-EDDHA? Is normal this dark red color?

Maybe I�m doing something wrong?
