The leaves won't change back you should note.....Look to new growth to "see" any correction.

The only "repair" that shows on existing foliage is N def....You have advancing Mg def....Use epsom salts or a high % Ca/Mg supplement to fix.......In hydro - 3 to 5 days for the fix to show in new growth.
