Early pre-flower

100 yes. Any stress factor can be a tipping point for pushing autos to early flip. Any kind of root disturbance past the seedling stage is a big no no. Also, autos are autos. There's a reason they're called cars. As they drive their own sex change. But, I fully agree with you. Stress can be a factor in early flip. But, as the same time, autos are autos.. I've not had a flip that young. What's that 12-15 days old. Real young and small. Hmmm. Is it worth your time.. yes, throw it in the corner. As if you're set growing with autos. This is the bad that comes with the good. Good Growing
