Reduce padding between product information blocks

[Leigh_Bart]

Trying to decrease the spacing (or increase) between blocks with in the Product Information section on the product page. 

Using the Concept theme: https://themes.shopify.com/themes/concept/styles/harmony/preview

Any tips would be greatly appreciated.

Thanks for the reply. Can you expand?

Sure, I can adjust the section padding. But I can't adjust the padding (spacing) between the blocks within the section. There are no padding options.
