Pre flower or showing sex hard?

6 weeks old. a single T5 Bulb over the green house.
This is my outside grow but its in the green house for 5 weeks.

10 days ago I have been hitting aggressive with grow nutrients so I assumed this.

1. Showing sex hard.
2. Vegging fast, so fast it cant keep up.
3. Sure white pistols,
4. No Calix.

The brown spot is from topping.

They are in airpots.

This time of year its already long enough days to just put them outside.

Ideas?

More, also this the same method I used last year. Single T5 Bulb on a timer.
Its not all of them just a few and most are the same kind, Mr Nice.

I be glad when im out of a tiny space!

They might've thought about flowering but they'll veg out of it no worries
