first grow attempt

im using 2 new t5 bright lights, as well as 1/4 strength nutrients + 5.8 water pH. one plant looks really weird i will point it out and I was wondering if you know either whats wrong with it or what strain it is (Number 5) - i got random seeds from friends. also were wondering if they look healthy - i have a shitty quality camera phone so sorry about that lol.

(this is after a 10 days.)
