Droopy-Curling Leaves

RDWC - Four plants in my system. 40 gallons total. I have a chiller, I use hydroguard and orca. FloraSeries Nutrients.
Ppm 350
Water temp 65
Air temp 78
pH 5.7

Started as clones with large root balls , very healthy. Added to system 6 days ago. One is happy as a clam the rest are very droopy and curled leaves. They all have great root growth at this point and have just touched the water with one or several roots.

They look thirsty. Are you getting much ph drift. I‘ve had some varieties that were sensitive to ph swings (like half a point) and they’d get droopy looking like that. How dry is your room? It won’t hurt to bump the humidity up if it’s low.

nah pretty humid actually been running a dehumidifier it's at like 55-60 with the dehumidifier

If I add nutrients how long would it take for me to tell if there burning the plants?

55-60 is great in flower. Veg can be more humid, 60-70 easy. I’d bump the humidity personally.

You could see the leaves start burning up in as little as a few hours if it’s super hot, but most often you’ll see results in 12 to 24 hours if you make a big change. A few days for leaves to start greening up in hydro.

Could it be not enough nutrients? I bumped the ppm to 700 and there all loving it. No nute burn or anything. 12 hours in so far.

If they look good then it should be ok.
