Edited photos have reverted to originals on iphone
In general, no. Assuming you don't get any of the "long shots" below to work, you'll have to re-crop and re-edit the photos from the originals.

Photos keeps only two versions of an image by design - the original photo and the current edited version. Other apps like Aperture save undo and redo actions and perform non-destructive edits, but not Photos or the iCloud photo library.

Unless your phone still has those images cached and would upload them, you likely lost the edits.

Here are the "long shots" for looking:


Look in the Recently Deleted Album (online and on your device and optionally on another synced device if you should have them)
Look for upload paused on the iPhone (scroll to the bottom of the content on the All Photos Album
Check for iOS backups after you made the edits - you might be able to restore that backup and interrupt the iCloud download of the non-edited versions.
