I've not done soil, so I'm not sure on the flushing. 80 seems like a good temp(85 is probably pushing it), but if that is the room itself, rather than the top of plant temp, then the plants are hotter where the light hits them. The wind is just something I noticed with my own plants. mine doesn't oscillate, but I have it pointing parallel to the wall, toward a corner.. I am letting the wind bounce off the walls, basically, rather than straight onto the plants. I have 8 bulbs on 2 plants, and I keep a close eye on the canopy temp. You could just back the lights off a bit, too. Mine are more adjustable, so I kinda fiddle with them once a day to get them where I want them.
