u can start feeding them with little amount of NPK in a small ratio like 20.20.10.Muhammad Bilal wrote:when there are 4-6 true leaves of a baby plant u can start feeding them with little amount of NPK in a small ratio like 20.20.10. But it depends how enrich or poor is ur soil with its nutrient value and wt is its pH value.
Higher salt amount may kill ur new baby plant.
If plants are in container, dilute a 1teaspoonful of fertilizer in 1 gallon of water and apply it to the new plants. and if the new plants are in beds then spread a little amount of fertilizer and water the soil. hoe the soil before to add the fertilizer.
Usually, I donot recommend new seedlings to fertilizer them specially when u have well loamy or bhal soil enrich with organic matter and good pH value i,e 7.
However, for healthy, nourish young plant and fast growing 20.20.10 water soluble fertilizer per month is enough.
What is a little amount? How much N PPM?
What is a small ratio of NPK? to a lay man like me a ratio of 20-20-10 is the same as 40-40-20 or 4-4-2 or 2-2-1. Only you require ten time more 2-2-1 then 20-20-10 to get same parts of PPM {Nitrogen per Million (or same strength of NPK)}.
If plants are in container, dilute a 1teaspoonful of fertilizer in 1 gallon of water and apply it to the new plants.
One tea spoon full of 20-20-10 would be about 5 grams, dissolved in 1 gallon (4500cc) will give you a solution having over 200 parts of Nitrogen per Million parts.
SAKATA Culture sheets recommend starting with 50-75 PPM N.

As you are in a position to recommend, I like to ask following questions
The main questions are;
What ratio of NPK? at various stages of plants life.
How much?
How often?
For containers?
For beds?
