Brown withering leaves? 2 weeks into growing

I put this plant into my hydro system exactly 2 weeks ago. It looked very healthy at first. Looked at it one morning and the leaves were brown and withering upwards? It looks like the growth is alos being stunted as well. What may this be from as all the other plants in my system look healthy but have orangy brown spots on them? Can anyine help? Lol thanks!
