Help, not sure whats going on with these clones

i got 5 clones, 3 bubba larrys and 2 tahoes. i put them in my new dwc setup on wednesday and now its saturday night. they have grown nice roots but the plants havent changed much, but the leaves became very droopy. sometimes they look a little less droopy but they are still pretty droopy. but it seems the roots are still growing. i used technaflora "recipe for success." and the water i used is this filter called zero water, it makes my tap waters ppm down to 1-2. the temp is usually around 70 and the humidity is usually around 40. my water/nutes are a little higher in ppm then i wanted, i did about 1/2 dose and the ppm is around 550-600 after adding ph down also. what can be wrong with my plants? can it be too high ppm? shock of transplant? too much water? i changed the light schedule from 24/0 to 18/6, but since theyve been droopy i put it back to 24/0.. any1 know how i can save these babies?
