I got them about four days ago they have grown 1 inch since then. I transplanted them into Tupur soilless mix. I have watered them twice with tap water 300 mL each. The room temperature stays around 75 to 79Â° during the day and 67 to 70Â° at night (Fahrenheit) Room humidity hovers around 37% to 43%. I am using 1000 Watt MH Please help first-time grower. If you have any tips on how to get my humidity higher I would really appreciate it. I'm currently running two humidifiers to keep it at that percentage. My room is 5' x 6' x 8'. Now down to the problem, The leaves have brown spots on them ranging from tan to a light yellow. It's only on the bottom fan leaves they also seem to curl inwards.
