Should i allow scrolling into whitespace?

I'm currently developing an android app. In one activity i have a Collapsing Toolbar which has:

• A title
• An image header
• 3 tabs

2 of the tabs contain scrollable data, and upon scrolling the toolbar collapses.

Now in the 3rd tab, there is only a few lines of data that the user is interested in (the rest is white space). If the toolbar isn't collapsed it looks pretty good. But my question is if 2 of the 3 tabs allow scrolling should i allow scrolling in this 3rd tab even though it would only increase the whitespace?

EDIT

Here are some screenshots of the tabs: imgur link

Note that the image header is currently empty. And all data is prototyping data.

Hope this helps :)
