Looks like a beginning nitrogen deficiency. A good dose of nitrogen is necessary now. Keep an eye on whether the younger leaves are also slowly getting lighter. And if possible, check the pH level as well; the problem might be coming from there.

Leaves have been getting more and more yellow the past week, with progressively more brown tips.Vpd has been pretty close to ideal, the pot had 1 gallon less soil so could be missing out on some nutrients? Possibly Potassium? Otherwise not sure what it could be. Does not appear to be N deficiency because the leaves are affected from the top too. What should I do to fix this
