Deficiency question

When working with an Aeroponic setup and when i spot a... say potassium deficiency the leaves look damaged.
So when i correct that deficiency do the leaves heal themselfs, or will i have to wait until new growth comes to see if the nute levels are good for the plant?

Most likely you won't see a leaf 'heal' itself. The plant will usually push energy into pushing out new leaves. The plant is perfectly capable of deciding how the nutrients are best spent. When correcting nutrient deficiencies look to your newest growth for signs of improvement.

great! thanks for your answer
