That is pretty hot, maybe get it cooler inside by window and flush it with water to get rid of the miracle grow. Dont think that bugs are an issue but would not hurt to get your microscope and check it out but def get to cooler spot and flush it. Dont give up I have had them fall over and look dead and a week later they are kicking but. if it is not dried up it still has life. Maybe guys with more seedling exp will chime in, I grow from seeds and that has happened but only a couple of times and they made it only to have me kill it later in life with nutes and bugs. lol
