Hi there everyone. I am going to be starting my first indoor grow in March. I have 2 questions about Cal-Mag when using Coco Coir with Perlite. Should you pre buffer your mixture with Cal-Mag treated water, or can you just use PH tested water at first? Also do you still use Cal-Mag during flush, or just PH tested water? I appreciate any advice. I will post pictures as i get going.
