Did I make the right diagnosis?

3 of my plants started drooping last week, one with brown spots. I hadn't checked pH of water/soil recently so i got my kit out. The soil runoff was 7.4 and the water going in was 7.8

I immediately flushed with pH'd water on all the plants. Now runoff is 6.7. They got their first feeding yesterday.

Does this picture look like too high pH caused this? They are still growing very fast and new growth lacks these spots. This is the only plant with spots.
