Not a problem itself, would just be neat to have!

Describe the solution you'd like
Would love for us to be able to have secondary output and add a chance option to primary and secondary outputs!

I have updated the format for ore growth recipes and a recipe can now have multiple drops, a chance of obtaining a certain drop, and drops for specific growth stages.
The updated format is available in version 1.1.0 of Ore Growth and I have updated the example on CurseForge and Modrinth accordingly.
Thank you for the suggestion!
