The second picture shows substantial improvement over the older leaves. Old damaged leaves do not "repair". New leaves will come out having improved appearence in acordence/w the level that you adjusted the fert. If well enough, the new leaves should be without holes at all. I would allow at least a couple of weeks before doing another adjustment. Takes time for the new level of fert to completely "fix" the plants ability to grow properly.
If problems/w nitrates happen as a result of the new doses, K2SO4 can be substituted for 50% of the total amount of KNO3 you are dosing. The NO3 adds to any nitrates.
The K2SO4 has non of this, but has slightly more K(potassium)@ 50% of the dose.
The shortest distance between any two points is a straight line...in the opposite direction...
