Transplant question

So I transplanted my plants(grown from seed) which are about 10 - 12 inches tall, into 5 gallon pots last night, and put them under my metal halide lights for veg. I used Mycos miccorizae in the bottom and sides of the holes and made sure that the roots were touching when I transplanted and backfilled. Also made sure that the new pots were drenched throughout with fresh pH'd water after. Just to where water was starting to come out the bottom. I know that plants can go through a little shock after transplant, and mine started showing drooping about 8 hours after transplant. Soil is still plenty damp so I'm not going to freak out and overwater. Question is, is drooping pretty normal for transplant stress, and how long does stress usually tend to last before they perk up?

Very normal... When I run into any problems with clones I cut some of the big leaves in half to take the stress off the plant.
