To me they look thirsty, but without a diary and more information, this is only a guess.
Need to know things like strain, auto/photo, light schedule, water amount, soil/coir/hydro/dwc, nutrients used and how much, type of light and temps/pH.
Just looking at a photo and giving specific advice is nearly impossible without the basic details of what you are doing in your grow.
Probably too many things to list in the "Question Section", but starting a basic diary is really easy and a perfect way to provide all these details.
Hope this helps,...
