Definitely not a nitrogen deficiency. So don’t add more nitrogen you actually have a toxicity on some plants. And based off the overall dark green colour throughout your plants it’s not nitrogen. You are more likely dealing with a phosphorus deficiency if I had to guess. Which is typical for plants in this stage of flower.

I put nitrogen but it keeps going !! I put half the specified dose on the bioobizz grow can (1 ml / liter) it's the first time I grow up in life !!!

She needs nitrogen my friend. The lower leaves turning yellow is the plant eating herself for nutrients. You need to add some nitrogen to your feed one dose should be enough to clear up all these leaves and encourage fresh growth. Looks like your in flower so I take it you have switched to a flower feed now alot of these dont have much nitrogen in as they are ment to be used with other feeds so what I would do my friend is give her some of your veg feed and that should clear that up :) Just remember mobile nutrients are in constant use by the plant no matter what stage of growth you are in she will always need NPK :)
