Too young for calcium deficiency so I suggest reading about leaf septoria.

Okay will do , I was looking and I saw rust fungus looks similar but it’s not under the leaves at all or maybe even a (P) deficiency

Prevention is best. Keep an eye on it. If a fungus such as septoria sets in it's usually slow and limited to a few leaves. Then it can become worse quickly.

For me it nit burning .
You have to adjust your ph bro
Your plants can’t absorb some nutrients by the way you water them.
Watering by 6.2 ph for soil is recommended
