    I have been using this product for a while now, I love it!
    I use it when I am making my hydro solutions, I mix Master Blend Tomato Special 4-18-38, Yara calcium nitrate and Magnesium Sulphate, makes a perfect hydro solution, best part is you can make adjustments to the mix as needed for what you may be growing. Highly recommend. Keep up the great work Custom Hydro Nutrients . com!!
