this is your problem, distilled is not good for growing, it pulls minerals to replace what was removed. r/o is ok as long as your nutes have enough cal/mag in the base.

agree with the above, i run 0-6-9-3(calmag)

Yup, magnesium deficiency starts on oldest leaves while calcium deficiency starts on newest leaves. So a magnesium deficiency is a good bet. Gotta add that cal/mag!
