first grow ever! how do the look so far?

hello everyone this is my first grow im using a bubble system I have two babies from a random dank bag, there in genrally hydroponics nutes and the lights are 200w of 10,000K I just bought a 400w hps and a 400w meatle halid as well. cant wait for them to get here, but anyways how do they look for being 16 days old?

whats up with all the little leaves on the branch points?

Looking good.

since im not for sure what the strain is how long should I veg? ive got a 2x4x6 space but i still want to keep them short
