The first picture is kind of blurry... but looking at that 3rd pic, it looks like they're undergoing a bit of heat stress. How close are your lights and what's the temperature at canopy level?

81 degree at canopy level .2ft above the ladies .the leaves have looked like this about a week. They look a little better after feeding yesterday .may I ask why I need to stop spraying the leaves .thanx guys

Agreed. Definitely don't spray for the reason Merlot stated above. If you're trying to foliar feed, make sure to do that either during/or right before the dark cycle (I personally never foliar feed unless im trying to correct a deficiency quickly). If you're just trying to raise humidity because it's too dry, put a humidifier in there... you can get one from target for like $30-$40. It'll give them a nice mist and raise humidity of the room without leaving those large water droplets on the leaves. Here's the one I use: http://www.target.com/p/crane-drop-ultrasonic-cool-mist-humidifier/-/A-11036853#prodSlot=medium_1_1&term=humidifier
Also, you may want to figure out how much lumens your light is putting out and go by this chart for how far to keep the lights from the canopy: http://www.thctalk.com/gallery/data/500/HPS-Light-Distance-Chart.jpg
To re-iterate, those leaves definitely look heat/light stressed. They curl up to help retain moisture because the heat (sometimes in combination with a fan blowing too hard) dries out the foliage too fast.

Thanks man I pulled the lights back a little and every thing long superb lol

Yeah, man... I wouldn't even worry about your plants stretching at all from pulling the lights back a bit. They look like they're growing super short and bushy so a little extra distance shouldn't hurt. Post some pics next week and keep us updated. I'm curious to see how they'll look. Good luck!

Very unlikely, to me it looks like heat burn as the fan leaf corners are turning inside out.

No bugs here man lol it was heat and a little bit of nute burn and needed magnesium

Looks like the heat curl is going away, but it's kind of hard to tell from those pics because of the HPS. Are they looking better in person? They've definitely grown a lot.
PS. Check out my journal if you get a chance. I'm about to post an update
