I water the plants with distilled water, ph'd at 6.2 and I add 1/2 tsp per gal of calimagic. This is happening on one old growth leaf on 2 plants.

From the looks of it, it looks like a leaf dying from not getting enough light which is completely normal. Hopefully, I answered your question and remember " Happy Growing".
