Hello student,

Hope you are in good health , so the answer to your question is "NO" NEET correction window will not be open again for editing , but according to me you should'nt be worry about the same because at the time of counselling they will check  all the documents and 12th percentage  will not matter if you have scored 50% in all the three subjects but if you haven't score minimum 50% in all the 3 subjects i.e physics , biology and chemistry then you will be in a big problem as you will not be eligible for admission in NEET then.

Hope this helps!
