1500 is freaking high, thats your problem. I am soil and I push at 1300. Max. I was going up to 1400 and once I lowered it to 1300 my garden responded with gratitude.

Curling up could be a heat problem. I grow aero and try to keep room temp under 80. Water temp is best in the low 70's. Your nutes are fine. Some strains will take up to 3000ppm. I run mine from 1400 to 2000ppm, depending on which stage of groth they are in.
