You might as well leave them in flower, or you'll risk some stress-induced problem such as hermie...

You started flowering when they were 4 inches tall, so if you let them just go on & flower out they'll probably be somewhere between 12 & 16 inches tall at the end.
I grew out a White Widow the same way, started flower at 2 weeks/4 in tall, and here's what she looked like at the end... 18 inches tall & pretty much solid bud from top to bottom.
