I have a plant, its about 1 week old, in rockwool, on a wick system, and it seems to be dying. Currently i am using 2 incodescent growing lights (getting a 400 w hps/mh friday), and they are fairly close to the plant, prob about 6-8 in away. It started off good, and i have 4 other plants that are doing very well. I changed the water today, and added nutirents. I only added a very small amount of nutrients in their "germination" stage. It is not browing, but more or less drying. The leaves are curling up. The Ph seems good, and should be fine now that i changed the water. It also has a suffiectient ammount of watter, the rockwool is always moist. What could be causing this.
