m0useanswered grow question 3 years ago Typicality they say not to transplant autos but if you are gentle it will be fine.
However I don't see in your diary when you transplanted them?? they always seem to be in the same airpot?
I would keep them this way, that pots big enough for their lifetime.
Airpots are one of the best systems I think to grow in. I want to get some for myself but my grow shops always out of them.
Autos tend to show pre flower around week 4/5. Sometimes earlier, Then they will go into flower.
It is true they can go into early flower from stressers like nutrients, heat or root disturbances.
I don't think that's your case when checking your grow.
If anything you have a solid setup and the plants look good.
Best of luck and Happy Growing!
