I haven't heard of 'Cal-Max', but I use 'Cal-Mag+', at 10ml/gallon, for RO/distilled water, or 5ml/gallon, for typical tapwater ... it's the rule-of-thumb I've used, and had good luck with ... :smokin:
the image reaper Reviewed by the image reaper 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
