I have a two week old Northern Lights plant growing from seed in Miracle Gro Organic Soil. She is currently under one 26W CFL for 24 hours a day. I plan to switch to 18/6 any time now. I water her with distilled water when she's dry (usually every other day or so). Yesterday when I watered, I mixed in a very small amount of Miracle Gro All Purpose Plant Food to try and perk her up. I know she's a little young, but I didn't know what else to do. She was doing well for the first week, but has been looking worse every day since. It started with some brown/purple discoloration on the edges of her leaves. Then her serrated leaves started curling down a lot and her cotyledons started yellowing. And today, when I woke up, her leaves were starting to turn white on the edges. I've tried to diagnose her myself, but all of the pictures are starting to look the same to me, and I'd really like to get some advice and opinions based on my picture. Any help would be greatly appreciated!!
