leave the door open when the lights are on, post a comment in my journal asking for help, im sure theirs plenty of people their that will come in and tell you a whole lot more than i can, just post a comment saying help needed, and explain whats happening and say you got pictures up and want some advice before it gets to bad, ill post a comment as well but you post a comment so people have got a link to click on to get to your journal, id hate for it to all go wrong at this stage so ill do what i can to help, id check temp and humidity and post the results in your journal, if you have got a fan blowing on the plants hard then turn it so its blowing above the plants and is just gently moving the tops of the plants, and give them a good drink every 2 or 3 days, if you can push your fingers down the side of the pot and push them down 2 inches, if you pull your fingers out and its all dry then it needs watering asap, dont go drowing them but give them one good drink and watch the run off and stop when you got run off out the bottom, so gently pour water all around the pot and not just one side of the pot and keep pouring slowly until you see it coming out the bottom of the pot, if their is no run off then poke some holes in the bottom of the pot to rule out root rot been the cause.
but as mentioned the leaves are curling up so thats high temps so you need to get the temp down, leave the door open when the lights are on, you could build a hood that directed the lights onto the plants and still have the door open then just close the door when lights are off,
post a comment on my journal and maybe someone like teSmp can offer you some advice or someone like x, theirs plenty of people on their,
