I'm running 3 1350k lumen 23 watt replacement as well as a 2700k cfl bulb in a grow box, temps been kept between 72-82 for the past 3 weeks (It spent about a week in the 80s while i was getting ventilation figured out). The temperature has been fluctuating a lot and im using FFOF for soil, no nutes added yet. Plants transplanted about 3 days ago. The browning on the tip occurred on only one leaf, which I found kinda strange.
Here are the pictures.
