1kodahanswered grow question 10 months ago I am contemplating something similar next round so researching now. Some strains give you an extra week or 2 in veg. On the diaries page try filtering for autoflower, topped, harvested.
I've been using that to get a handle on potential success or failure as well as a tool to narrow down which strains might be able to recover well enough to make it worthwhile.
Good luck with your current grow.
