Mysterious Wiltage

Is it light shock? I put the rockwool into cups and moved them from T5 floros to 400 watt MH 48 hrs ago and the sour gapes especially is wilting a bit. The six on the right are all slumping a bit. The front 2 in the far right row are sour grapes and the other four there are purple kush. The left 6 are Blue Dream. They were put there 4 days ago and I think they slumped first too but not sure. watering is regular, MH is far away, nothing poisonous in the environment. It's light schock right?

Shit it's not letting me upload photos right now. I'll stop by tonight and try again if I don't have any answers

Bump. Dude I even took diff pictures and it doesn't help so I'm thinking it's RIU and not me. Please give any input, thx

You may have taken more pics but they aren't posted in this thread bro
How close are the clones to the light? What are the temps and humidity?
I have never had a problem switching my clones from t5 to HPS
