When to start flowering ..

Hey, noob here. I was just wondering your guys's lovely opinions on when I can switch from vegging to flowering. How long do you guys typically wait? Or how tall do you let them get? Thanks!!

6 weeks(10-12in) if your in a hurry, the longer you veg it will increase the yeild

is your plant a indica or a sativa. or a cross. need to know that first before
we can tell you when to start flowering

it's not by height ur plant can be strecthed, alot of on here do it when the plant has 4-6 nodes
