Just went in and watered the plant and noticed that my other germinated seed finally sprouted. any ideas on what to do when that plant is in veg and the other is in flower? I only have one grow room. Maybe during the time the light is on but the flowering plant needs darkness, just cover it with a big cardboard box? Or just take the new plant outside to get daylight while the flower room is dark?

Also I have noticed some leaves are looking nasty. Some are getting sickly and curling down and in, and some look fine. overall, the plant looks healthy. Im not sure what this is from...maybe ph? I just started ferts (12-6-6) once a week, so im not sure whats up. More pics soon, I need batteries.
