Help with droopy plants. Thanks in advance

[SmittyB..]

Hey everyone. Thanks for clicking to help out. All seedlings are 2 weeks from seed. The bigger plant was moved in so to space which is about 2 weeks older than the seedlings. I have been dealing with droopy leaves for a couple of days. I have changed out res water with plain RO water phd 6.0 and I’ve also changed it back out with ro phd water and 100 ppm on .7 scale just botanicare grow. I have turned oscillating fam off and back on after no change. Fan isn’t blowing directly on plants. I’m really confused. I moved the one bigger plant from one rdwc to the other and all plants in this particular rdwc are dropping. The only other thing I can think of are the res temps. I use a chiller in this tent and temps are at 69? My other tent stays at 78-79. I have more photos but figured these would do since they’re all doing the exact same thing. Oh and I’m using an HLG 650 turned all the way down?!?

If your PH and res temp are in check then the next 2 things to look at are your lighting and fertilizer. If you're only running 100ppm you're starving the plants. I start clones at 650-750ppm in my spray cloner. I would increase your fertilizer strength to 500ppm. Increase from there gradually if you see improvement. In veg 600ppm is plenty unless you've got monster pants. 650-800 is more appropriate for flower. They don't look horrible by any means. Just gotta get your fertilizer in check. I see no problem with the lighting if it's dialed down to the bare minimum.

Thank you. I have ran rdwc a few times with no issues. I absolutely love hydroponics so having ran low ppms before with great results, I never questioned it. So when I get home I’ll up the ppms and see if they don’t starting reach up again.
