I water with RO water 10ppm I then add from 220 - 250ppm's of calmag. Just like the Doc said. Calmag is gods gift to plants and is very important to coco. Remember that most coco needs to be charged before you use it. Remember to flush your plants frequently to wash off some of the salts that have built up in there. Stay away from hard water that will also mess you up and cause lock out.
