Maybe larger (640*704) training images are not better than normal (512*512 or 512*640)... At least I tested for hours and outputs are not satifying enough.
Maybe set your resolution around 640*704 before (or without) Hires.fix would help get better results.
Description
Higher steps. May varies only a bit from v2.5.

Here is my suggestion:
Train them with 512x512, use chilloutmix_Ni as your base model.
