Plants Look Like Theyre Trying To Fly!?

my plants look like there trying to fly! is this normal?

plants are 7 days old (BRAIN STORM strain from marijuanaseeds.nl)
1000 watt Solar Max bulb 2.5 ft above plants, 18 hr cycle
very mild nutes (quarter strength or less)
PH is 6.3
water cycle every 3 hours, except when lights are off.(last watering at 11:45, darkcycle 12PM to 6 AM)

thinking maybe heat or humidity problem?
or do they look OK?!

They look perfectly normal

its cool dude, dont stress. new growth looks like that until the leaves grow and stretch out. they'll look normal again soon.

thanx 4 the quick responses, THIS SITE ROX!!! this is my first indoor grow, and hydro experience! pic in my avatar is of one of of seven clones that i got from a buudy and planted in the backyard flower gardens. harvested just over 2 lbs! the best part is that i HERMIED one of the plant, (and that was the only garden that had two plants in it and it pollinated the other, so i let her go a bit longer than the others and got an ASSLOAD of seeds from her!!!) noot sure what strain, clones were brougth from Cali. kick ass bud!!! definite hybrid. I also have 4 of them seeds started in soil, i just tagged them my BYS (Back Yard Suprise) strain. i'll get some pics out!

they just reachin for some good light lovin.
