My auto critical orange punch is starting to flowe...

Nothing. That is why it is called an auto flower, nothing can prevent it flowering.

I wouldn't worry about it. You still have plenty of time to train it into shape you want, you could keep on the veg nutes for a bit longer to try and keep it veging a bit longer. Not saying this will work as autoflower tend to do what they want when they want.

Hi mate, theres nothing you can do to keep her in veg. Autos set their own schedule. Shes looking great! Hope this helps and good luck with the rest of your grow 🙂
