Droopy seedling leaves

Hey guys,
This is my first post and also my first grow so please excuse any ignorance on my part. I started my DWC grow on July 1st so it's still in the very early stages. It's a very small 6 quart reservoir in a 18w x 13d x 48h grow box under a 300watt Mars hydro led. I'm using the GH trio with calmag at 1/4 strength along with hydroguard. I germinated a Nirvana Lemon OG Haze auto in a rapid rooter. Current PH level is 6.0 and current ppm is 473. Current Temp is 81F and RH 51%. Light was around 30" away but I recently dropped it to 24".I could just be being paranoid but I feel like my first real set of leaves are very droopy compared to the "healthier" seedlings I've seen. My reservoir water was just about touching the bottoms of my net pots as of this morning so I dropped the levels down a half inching thinking maybe she wasn't getting enough oxygen and that was causing the drooping. Any input is appreciated. Thank you in advance.

Still growing, still green, and still drooping. Ph: 5.9, ppm: 481, 82F, and 49% RH. Rapid Rooter was still very wet even after the drop in reservoir level so I dropped it another 1/4in and moved the air stone a little farther away from the net pot so the bubbling doesn't saturate the Rapid Rooter.

I just ordered a small 6" circulation fan yesterday so I'm hoping to have that by tomorrow. I will say that the inside of the reservoir is holding onto a lot of water. I'm having a very hard time keeping the Rapid Rooter damp without being soaked.
 
🌱 I bet keeping the Rapid Rooter dryer and leaving more of an air gap below the bottom of the net pot will help at least a little. When a plant is drooping it's either completely dried out or something is preventing the roots from getting enough oxygen. In soil, drooping happens when there's so much water that there are no air gaps to provide oxygen to the roots. In DWC, droopiness can be caused by it being too hot (hot water holds less oxygen), by there not being enough bubbles in the water, not being an air gap under the bottom of the net pot, or some type of root disease like root rot or algae. If you peak carefully under the lid through an unoccupied net pot, do the roots appear to be white? Is light getting in to the reservoir? Are you using a root supplement like Hydroguard or Great White to help keep roots healthy? 🌱
 
Roots look beautiful. Super white, almost clear. I'm thinking it's more of a lack of oxygen problem. Hydroguard is being used. What do you recommend for lowering reservoir water temp in a small 6 quart system? There is a 1.5in air gap between the pot and the water. I feel like there is a good amount of bubbling from the air stone.

Roots as of right now. A guy on Grasscity also suggested lowering my ppm so I've dropped that down to 350 and added a circulation fan as earlier suggested.

🌱 What are you using for an air pump and air stone? For some reason I could only see like two bubbles in the water in the pic. The reservoir should be roiling with bubbles to make sure roots get enough oxygen. 🌱
 
I've got the stone pushed farther away from the Rapid Rooter because the net pots are so small and I had no room for people coverage with the Rapid Rooter in there, so when I had the air stone directly under the net pot, the bubbles were soaking the Rapid Rooter. Since I moved the stone over and dropped the water level, the RR has gotten a lot less saturated and is looking better. But that's only been since last night so I'm still waiting to see changes in the plant.
 
I hadn't planned on it. I bought it to grow smaller auto plants. Is there a downside to a smaller reservoir in DWC other than having to top off more often?

I'm no expert, but I do believe she is feeling better this morning. The RR is also a lot dryer. I was seeing some nute burn on the second set of leaves so I added some PHd water and dropped the ppm down to 335. Can't wait to get home from work to check on her.

🌱 Yes, as far as I know, just the topping off more often. I just know I grew in a 2.5 gallon reservoir once, and by the end of the flowering stage I was filling it up more than once a day because the roots were so big I could only really add a gallon at a time and it was going through that in less than a day. But I also let the plant get way too big before I switched it to the flowering stage (it was two feet high at harvest). Since you have an auto, I doubt it will get as big! 🌱
