It is very difficult to differentiate the spots due to high background light. Please upload few more clear images. Thanks

it looks like early stage of nitrogen deficiency, perhaps due to rapid plant growth (roots cannot provide enough macro elements) .

Yes I think so!! even the stem is very thin! and the leaves are big and large, disproportionate compared to the stem and the roots.
