Clones looking droopy.... please help

Plants are about two weeks old, under a 1000 watt HID right now. They were originally in soil when I got em about a week ago, and I put them into my Sunshine #4 in some start pots. They had no transplant shock at all, unless it was somehow delayed. Today, they look a tad droopy to me. I have watered them when the soil 2-3 inches down was completely dry, so my problem is def. not over-watering. I am getting another 30-35 clones later today, so I would like to diagnose this real quick and get rid of any plants if they are sick - only have four right now. I will try to upload pictures soon.

One thing I can think of is that when I did the transplant, the rock-wool ended up closer to the top of the Sunshine than i wanted. Maybe the rock wool is drying out too quickly? I have no started using nutes just yet, figured they were probably still getting some from the soil. Anyone have any ideas? Will post pictures later

Did a little reading around the forum, maybe the very beginning stages of a sulfer diff. it looks like to me? Leaves are not yellow at all, just droopy and a bit more pale than I am used to. Any help is much appreciated, as I said I will do my best to get a picture up shortly. Need the girlfriend to get home quick!

P.S I am using water with a ph in between 6.7-7.2. Can't be exact because I use that little crappy ph tester. Help!

One last thing, the stems around the top of the plant have traces of purple in it. Any help is much much appreciated!

I think it is a sulphor diff. after much reading on the forum. What do I do? Is this def. the problem? Please help. Also, are these plants going to be more vulnerable to disease? The problem is about 12 hours old it seems...

If they are more vulnerable to disease, I might get rid of them before I get the other thirty five or so later..but I'd like to keep em. Someone help please!~

Clones look like shit in the beginning. The leaves they have now will be the half dead crap you trim off in a few weeks time.

Nope, I thikn they just needed water. I had a friend come by and he said they need water. Which is a bit deceiving because the soil-less mix was moist, and appeared to be providing the plant with plenty of water. Someone in the sick plant forum suggested that my leaves are letting moisture out quicker than the roots can take it in, thus the soil really doesnt have to be dry for the plant to be dry.
