1. Soil 2. 600W HPS, 15 inches, 18/6 3. Are temp is around 78 during lights on and around 72 when lights are off 4. Distilled water once every four to three days 5. Using Fox Farms Organic Ocean soil, 12 oz cups 6. 3 plants and they are 5 days old The one plant leaves are almost all yellow. Another one just has the tip of one leaf yellow and the other seems to maybe have a little bit of yellow around the edges. Like I said these plants are around 5 days old. Is there anything wrong with them or am I just being paranoid?
