Plants drooping, not sure if its overwater or underwater

Hey guys! It's my first grow and I'm growing 3 autoflower gorilla glues, they are all almost 1 week old. Woke up this morning to some droopy leaves, I'm growing in coco coir and feed about once ever 2 days, last feed was 2 days ago. They looked fine yesterday but some are drooping now. I also switched from a crappy 300w LED to a mars hydro 600w 2 days ago. pH of feeds have been 5.5-5.9, about 100-250ppm. What am I doing wrong?

Light too close?

No need for that big light on such little sprouts.

don't stress man they look fine, those big leaves on those tiny tiny little seedlings mine always look droopy at that age. Just keep doing what your doing and give it a few days.
