They don't look too bad to me...ck PH of the water your using and the soil and make sure that's all ok and if it is, (6.8PH or close) just start gradually adding some nutrients...maybe 1/4 strength at first, then if they like it, 1/3 or 1/2 strength...keep reading the plants so you know how they react to what your doing...No need to worry yet. You didn't say how long it was from the transplanting to the pics, so it could just be they are just a little stressed from the transplanting also. As they grow bigger and fill out, less and less light get to the bottom leaves, they die and fall off, nothing to worry about...perfectly normal!

PS Good pics!
