What issues do i have with leaves?

Looks like calcium issues to me. From PH or lack of it/lockout is the question.

I concur with others, certainly a calcium deficiency/uptake issue and likely a magnesium deficiency in early stages - leading me to question soil pH, water pH, and soil salt content. Make sure the soil isn't locked (even in pockets or locally within the pot) and dial in your runoff/water pH range and the issue should resolve.

Calcium, which in soil should not come up so early, so its wrong ph you put n. Soil range is 6.2-6.8 , but 6.3-6.5 works best.
