Hi!

The 3 macros are nitrogen, potassium and phosphorus. Higher quantities of nitrogen are used for the vegetative phase as you said. For the flowering phase plants need mostly phosphorus and potassium. It's important to use a lot less nitrogen during flower.

Plants use many micro elements including calcium, magnesium, iron, etc. that they need in smaller quantities. If you are using led lights you will need to supplement calcium and magnesium as well.

There is always a possibility of over fertilization, especially with mineral nutrients. Less so with organic bottled nutrients, and less so with organic solid nutrients.

@Creeperpark is very good diagnosis plant issues given a picture is provided
Burn is most common in inorganic fertilizers and organic during the nitrogen cycle
More common is pest as in fungus gnats and nutrient lockout from over watering

Potassium is represented by the symbol "K" on the periodic table,
which comes from the Latin word "kalium" meaning "alkali"
