Your nutes are low. Are you using DWC under your drip system? If so I would back down the drip, prolly put them on a 15 on /15 off timer Walmart $7. That tight curl looks like over watering. Also, drop the pH closer to 6 and raise your ppm to 700 with ladies that size. They can handle the nutes but not all the water!!! How deep is your res?
Other than that looks good. oh and raise your lights just a bit. infrared warms things that are close to it. like your big rubbermaid lid now, once their bigger and the lights higher, and the heat won't be anything a fan can't take care of.
