Is this a sign of stress?

Seen it happen to a few of my grows after i feed um water....the top leaves around the top are twisted or pointing directly up at the light....

Light: 450 watt MH 2 feet from tops
Temp: almost always 75-77 at the tips
PH: 5.5-6.0
Medium: Fox farm ocean floor (soil)
Food: CNS17 (2 weeks into flowering)

donno if im feeding them the right way...i will water them untill it comes out the bottom of the pot then wait till the are just about to wilt to water again but with nuts. alternating from water to nuts every feed

temps are good, ph is too low for soil? light may be a bit to high, they are stretching for it but does look like stress with the leaves curling

but I have also seen the leaves curl to get light

Ya i never figured out why every grow i do i have tiny brown curled tips on almost every leaf

one on the right looks awesome. that's when I know the ladies are doing well when they strecth to the light like that. The other one looks like maybe it's to close to a fan??????

i get the exact same problem, i heard alot of solutions, but its just one of those things, as far as i know it doesnt effect the growth rate or potency of bud- but a healthy plant is a healthy bud, so just take care these curling tips dont get to extreme, apart from that all looks good- healthy green leaves, peace x
