First off all the plugs in the first picture look really dry the other look kinda damp, you can pour 3/4 to a gallon of water in the tray so you don't have to water as much. As long as some water right under the plugs they will suck the water up. Also are you using a dome? Clones need high humidity so you should mist them every day or so if your using a dome. Some of those look roasted and aren't probably going to come back.
