Hi I am a newbie at this so be easy! I recently started growing vegetables from seeds. They are about 11 days old. Some of my tomato leaves are twisting/curling up. I have watered them once which was yesterday(the tenth day) and spray them with a spray bottle a few times a day. I have a heater set at 78 degrees and the light is about three inches away from the plant. Today was the first day I noticed this so I am trying to correct it before it gets worse!
