i am a beginner and i am growing some plants outdoors. i was wondering what the problem may be with a few of my plants. the leaves of some of them are turning a white color and curling. please help me out. the plants are 20 days old. I began the plants with a miracle grow soil with pearlite that contained some fertilizer in it: 18-10-10. I have slowly added a little soil on top of this from the mulch pile in town, the mulch is extremely organic and rich soil. I will try and post a picture later today when my camera is charged. Any help on diagnosing my problem would be appreciated. Criticism, suggestions, all are welcome. Thank You.
