That looks like nitrogen toxicity my friend. With high levels of nitrogen, nutrient lockout can occur. We need pictures of the whole plany not just one leaf though.

What is you pH at?

[radudima]

The ph level is 7.42

[Gjourney101]

Yeah that's a problem growing in soil. Get it down to 6 - 6.5. Make sure the water and soil pH are between 6 - 6.5

I had a suspicion that it could be about the ph level or about the assimilation of calcium,but being a beginner i need other opinions,thank s

pH should be between 5.5 - 6.5 otherwise your plant won't be able to absorb nutrients. Just like Gjourney101 said.

It’s the PH. Call the soil manufacturer and ask them what the ph should be. 7.4 is way too high for soil. Flush until you are closer to 6.5 in the root zone.
