Not enough moisture, roots at bottom of seedling container dried up, Also think I had light too close, seemed like it stunted growth.
Moved light several inches away and now it's stretching out a bit, going to transplant in larger 3 qt container with new all organic soil/perlite mix, worm castings for 50/50 for good drainage.
Plant Light stressed?
11 pm I switch from 100 to 1000 watt led. Woke up 9 a.m plant was drooping. Top 3" soil little dry so I watered with 5.8 ph water only, still drooping.
100 watt was 18", 1000 was 21" but moved to 25". Blueberry muffin seedlings responded great no issue.
For sure if you upgraded from 100W to 1000W and only adjusted it 3" it's a significant change for your plants. Hanging it higher was a good move. Your plants are healthy I wouldn't worry too much it will take a few days for the adjustment. Keep in mind your leaves will fluctuate from drooping to reaching from the sky throughout a daily cycle just make sure you don't overwater.

@DILLIGAF, Appreciate the help.
I put in a dark closet with fan going while I set up the tent 100%. Perked up and looked normal in 4 hours.
I put it back under the 1,000 watt light at 18" but ONLY have the dual 50 watt cree bulbs on not all the others. Added humidifier & fan, also now in the main 4x4 area not 1x3. Lights been on since 7pm its 2:30 am now they look good.
1st grow in 10+ yrs. 1st ever soil grow. 1st time using leds. LOTS to learn.
