Yellow leaves, nutrition, feeding, feedback

[saltybluegrass]

When you see a yellow leave/ brown spotted leave, curled leave...etc.
How long has a deficiency been around by the time she shows it?
And how long does a cure usually take to stop these outside evidences ?

Nutrient deficiencies can take four or more weeks to appear. It will take a day or two for the plant to recover, but the damaged leaves won't. The leaves will still perform much of their function, so don't remove them unless they fall off or it's part of a needed defoliation.

Yellow leaves like once a week maybe ok? Or singular leaF should I say?

A single leaf is not a concern. When there are more it's time to take a closer look.
