To much nutrients per H2o, looks like Nitrogen blast, pretty dark green leaves you have there, water the tops with spray bottle at night for a minute, ph your medium to 5.2. She will straighten out after a week. add water only, no nutes for a wk..I have dealt with this many times in hydrophonics. Especially with plants with large root systems. I have one plant currently that I filled with nutes, it is in a 5 gallon bucket in hydrophonics.Deep water culture. It took in 4 and a half gallons of water slash all the weeks worth of nutes in 1 day there was an inch of water left in the bucket 6 hrs after filling.this is what mine looked like at first also. I fill my bucket now every 3 hrs with a gallon of water and the leaves leveled out. watch for the yellow to come back to the tops once you see that give'er back some juice. She'll be alright. Hope this helps.

Try to take your photos in natural light.

Its hard to see the plant in orange/yellow light.

Just a thought...

the color is not the issue, the curling is

What peak temperatures are you seeing on light?

mid 80s
