It's a combination of over/mis-watering and light shock.
Your lights are so close that the leaves are literally twisting to get away from them, it's not genetic. See the thick, blistered-looking spots on the leaves on the second, third, and fourth pics? That's light shock. The growth pattern (the leaves looking like upside-down rowboats) also indicates that they've been fed with too hot of a nutrient solution in the past.
Get your feedings locked down (in terms of both fertigation and medium pH, frequency, and amount) and move your lights away and you'll be in better shape.
