it is a cal/mag def. when you use either of those waters, you need to add back the calcium and magnesium that was removed.

Your plant will not be able to absorb nutrients if your water or medium is locked up from a ph imbalance. Just ph the water and give no more than 1/2 the recommended amount for nutes. If your using coco or rock wool you will need to add cal/mag as Chuck says.
