You deficiency in maize is consistent with micronutrient deficiency, It looks to me like a Zinc deficiency quite common in maize on alkaline soils.
On researchgate access my treatment Zinc nutrition from the ground up.
If you harvest 20 leaflets and give atmoic spectrum analysis Zinc should be over25 avoid deficiency.
Applling zice foliarly can be proof of concept as the plants in a deficient state will regain green and grow normally.
5 kg urea and 2 kg zinc in water to coverage a hectare can be effective for foliar treatment.
Zince deficiency is very common in alkaline soils where maize is sometime grown.
Applications of high levels of phosphorus fertilizer can induce a zinc deficiency also especially in the alkaline soil situation.
