lol.. funny thing is, I got the same results when I googled Calmag.

It's from Grotek, he's the link

Cal-Max(tm) (Nutrients & Supplements) by Grotek - Organic fertilizers, plant nutrients, and hydroponics equipment
immortal420 Reviewed by immortal420 on . CAL-MAX Is it pretty much the same as CALMAG Plus? The mixing directions says 5-8 ml every 4 liters. I assume that's for regular usuage with city water, but what about for distilled? My plants have been getting the reservoir changed every week with distilled water, DNF Bloom A+B, DNF Gold, DNF Bloom Fortifier and DNF CARBOLOGIC for the past 3 weeks. I sense a deficiency... I foliar spray with DNF Gold and DNF enhance twice a week. Thanks. Rating: 5
