A question from a fellow grower:
I have looked at all the pics you have describing deficiencies and am having a hard time diagnosing. Maybe a fungus in the soil or shock. Perhaps a bug?

The pics are way to small to see for sure but some of the damage does look like almost a line or trail created by a bug.
An update:

More leaves have been affected and some of the bottom ones are dying.
These plants were fine in the potting soil. I checked them at night to look for critters—nothing.
Do you think it would be wise to treat the soil with hydrogen peroxide.
