My friend is growing just one plant. Its under one 150 watt hps light fixture in a growbox. The light is approximately 15 inches from the plant. The temperature stays around 84-85 degrees. Soil is Sta-Green which contains:nitrogen,phosphate,potash,,potassium,canadian peat moss, and perlite. Has proper ventilation and a fan flowing fresh air over and towards the plant. He waters every 2-3 days when the soil is real crusty, how much water should he pur into it?
The plant is exactly 20 days old, its approximately 5 inches tall with 25 visible leaves, Is this good or bad?
The problem is , maybe 3 of the leaves has very small yellowish spots on the outter tips of the leaves, and the other leaves look a pretty green healthy color. What could be the cause of this?
