No insects. A nat here or there but that’s it.

They were taken from led lighting and then In a cold van for 30 mins then put under 1000w hps. Any stress related issues?

Could be from the light change, the cold( how cold?), or even just abrasion during the move

It was about 30-35 degrees farenheight in the moving van.

We were in there for 30 mins.

Plants were then transported to basement (hit a wall here or there but safely for the most part)

Watering at about 600ppm to get them used to their new nutrient line

That'll do it. Likely the cold. Cells start to freeze/expand/rupture below 3C. I've seen a severe burn from being exposed to similar temps for only 30 seconds or so walking between buildings, it was windy too mind you. How bad is it?

Yep, that was the cold alright.
