It's not too late......the best thing to do is transplant into a larger pot with QUALITY soil and make sure you water them with water that is ph'd between 6.2-6.8 until they shape back up. Your twisted leaves will not fix themselves but the new growth should be normal. My personal favorite soil is Fox Farm Oceans Forest.

And get rid of the hydroton asap!
