Hey poetHoward, 

Welcome to the Photoshop Community. We need more details to help you.

To change a specific brush setting to its default in the iPad version of Photoshop, follow these steps:

1. Open Photoshop on your iPad and select the Brush tool from the toolbar.
2. Tap and hold the brush icon to bring up the Brushes panel.
3. Select the brush you want to modify.
4. Tap the three dots icon at the upper right corner of the Brushes panel to access more options.
5. Look for the option to reset the specific setting you want to change. Note that you may need to adjust the setting manually if there is no direct reset option for that specific setting.
6. Once you have made the changes, you can continue working with your brush as needed.

Let us know how it goes. 

Thanks, 

Shivani
