Leaves curling up and drying out? Help

Ok here's my basic info.

*Growing in 5 Gal pots in 1/2 MG soil 1/4 peet moss, & 1/4 perlite
*My pH is 6.0, soil meter
*My lights are 16-26 watt CFL and 4-40 watt T-12 CFL
*I'm on a 18/6 light scehdule, with 6 hours of natural light and 12 hours of CFL
* The plants are from clones, I've had them 2 weeks and they started out 3 in. tall
*I have not fertilized yet because MG has nutes in them, going to get Foxfarm
*Water only when top soil is dry down a few inches, normally once a week
*Using tap water that has aired out for 24 hours+
* I'm LST with hemp string
* the Temp: Closet 75 to 85 degrees/outside is 85 to 95 degrees
* Low humidity outside and med humidity inside
* no bugs no mold

Ok what I've done lately is put the babies outside with my pitbull, its been a little warm but not scorching hot. I figure real light is what they really want. I checked this morning and they needed water so I watered and the run off is very dark brown. I also noticed that the bottom leaves are curled up and dried out. Some leaves are curling up like a taco, and the ones that are bad are curled up from the tip of the leaf up. :-( I did have some yellow tipping on the leaves before I started putting them outside, and my pH was a little low 5.0. The yellowing of the tips have gotten worse sense I started the outside time. I'm going to do a basic flush this morning and see if I can get some salts washed out. Pics below, sorry poor quality but its all I have right now.

My question is have I done more harm putting them outside because its warmer, Is it too much nukes? I'm only using half MG so I figured they would be ok. Or is it something else. Thanks a bunch:-P

I just gotta warn you that moving them back and forth...indoors and out....leaves you open for a bug infestation. This is because indoors there are no natural predators....if you have bugs then put your plant in flower - ur screwed and your grow room is infested. Nothing from outdoors should ever go in your growroom. As for what's wrong...it's definitely not because of too much light. Read the link motox mom provided....lots of good info.
