Why is there so much yellowing? Its under a 150 watt hps sun system. I just added a fan which is not trained on the plant at all times. Its sectioned off part of my garage so fresh air does not always get in and at night a car is parked in there. The temps never get above 85 though. I had a friend grow this from clone as well. Its supposed to be pornstar OG, and he said his were finicky too. The buds look super small right now, should I be feeding it something else? The light is about 8 inches away from the plant. Ill add pics after I figure out where to upload my photo.
