fiming during preflower?

Can you still fim when your Auto just started showing signs of pre flowering or is it best to just let it go. I top'd at 5th node and was hoping i could get a fim in on the 7th node before she decided to pre-flower. I am not caring for how fast these seeds are flowering they are like dwarfs. I spelled fem wrong whoops

Most autos cannot take a FIM or Top as they are fixed in how long they are going to live.
They have NO time to recover , so if they get stressed they will stunt.

I say leave it , and just let her do her thing.

Preflowers proceed actual flowers by quite a bit of time. I'd say you can top now, but when she starts flowering you have to just let it happen.
