My seedling is 12 days old and the first set of the biggest have been stuck sticking upwards for the past 4 days now. I read some where that they could be reaching for light but i have 2 23 watt cfls on them. I also read that it coulb be from lack of ventalation so i move them to a bigger room and put a fan on them with the window open. I also noticed that there was so slight browning on the edge of the leave before i moved them, but after i did it stopped browning 4 days later nothing much has changed. I could give pictures but the plant looks pretty straight forward leaves up with browning on the edge. Im not sure whats going on
