When loaded down with a load of greater than 35 ohms the chip regulates the output voltage, ad under 35 ohms the output voltage drops. Why is it doing this?

LM2596 ADJ Vout drops with a Low Load

We’re going to purchase the uH inductor to try that as you have suggested. Apr 8, 4: I have attached a Webench design.

I would hold off on buying the bigger inductor for now. The load in the picture is 1k.
