The only info i could find on this, was saying that they need more nitrogen. I dont know. My plants are less than a week old, and the leaves a curling upwards. Other than that they seem healthy. I was going to put some pictures up, but i dont know if it's necessarry. The plants on a 24 hour light cycle, and i have yet to start feeding them nutes.
Again i can post photos if necessary.
