DWC. UPDATED PICS 1 Week Floweirng!

I am currently growing 5 plants. 4 of them are in hydro, and 1 of them is in some fox farm soil, in a small pot. I threw it in a little late, but when i found it at dispensary and saw that it was BubbaxMaster i couldn't help myself. The plants in the hydro are green crack in the front, blueberry kush and black domina in the bag. The black domina is huge! There is a runt in the front, (1 of the green Cracks) I had a minor nute burn issue early on which i quickly fixed. I am now seeing that the plants are a bit droopy when the lights are off, but when they are on they aren't droopy at all. The odd thing is that it doesn't have to do with the nutes, because the soil plant is was on a diff nute schedule and showed the same droopy look that the other did. Im in DWC and i leave a pocket of air under the net pots about an inch, so its def. not over watering. I have no idea! But i dont think its a huge deal, i turned the lights on to show the droopy plants in a few pics. But they are GREAT when the lights are off.

that droopy plant could be over or under watered but you should be able to know which one
