Willie Nelson and Jock Horror 6 inches tall no new branches?

Should I be concerned of new new branches yet? Huge as top leaves and showing signs of pistils. Im using 1000 watt hps 3 feet away cus of temp issues. They might just become super huge ass sativas, anyway this is only after 2 and a half weeks from seed so I am happy at least.

6 inches tall at 2 and a half weeks seems odd to me...Are they stretching?

Which Willie you running? Original by Reeferman or one from Barneys or from Gage Green?

Willie Nelson mixed with love potion Number 1. In fairness they have been 3 foot away from the 1000 watt hps due to heat issues but I think I got it figured out for the am. I also turn off the big hps at 7pm till 7 am and use the regular house light at night to keep them vegging. they seem to like the break. Its a delicate art getting them 1 ft away from the 1000 watters isn't it. They are looking very healthy and beautiful though. Nomites no nada nice and green just curious as to when I shall see new branches.
