If you stunted one with stress, yes it can come back. The question will be at what cost. Autos have an internal timer. You dont tell it when to flower, it does it when its wants (internal timer). So its like a race with an auto. You only have so much time to let it do its thing before it changes on you. So every time you stunt it, it loses potential yeild. So the question is how big it gets before it changes itself to flower. Is it worth putting time and money(lights/fertilizer) on something that wont produce much if it flowers on a small plant?
If I have space for it, I did, and I used it as a learning curve. How to fix the issue and what happens after. Had 1 plant produce .5oz for the whole thing. Super waste of time, but learned how I made the plant get root bound.
Now I run photos. You tell them when to flip. If you make mistakes, you can veg it longer and fix it. Easier to learn on. I averaged 2-3oz per plant with autos. I average 5-6 on photos with a slightly longer veg. Its just a better end result with photos, unless you have everything dialed in (environment, fertilizer, grow media, good genetics).
The other thing to watch for with stunting/stressing a plant is the chance of hermie. I've had a few plants hermie on me when they got a little too stressed. They came back looking healthy, but the damage was already done.
To me it looks ok and I'd keep going with it.
Just some things to think about,
Best of luck! Happy Growing!
