Hey oldschool do you ever use epsom salt? Sometimes find that they are asking for more mag in coco and the extra ca isn't really needed. Botanicare recommends minimum 5 ml per gal in coco. So I usually do about 300 ppm on the 700 scale and then add about 70 ppm of epsom salt. Plus for like 2 bucks you get a few pounds of it.
