Looking better! Keep in mind that the damaged leaves never recover, so keep an eye out for new damage. I tend to pull off the damaged ones (if there aren't too many) to make it easy to spot new issues.
Curled leaf edges on the uppers are usually light stress, and it's very possible that your nutes happen to land close to the sweet spot for hydro, but you'll only know it for sure with a pH pen.
