That round of nutrients seemed to do well. I can't raise the light any higher now. A few fatter, lower fan leaves had tips that were dying, so I removed them from the stalk. Got myself a gnat issue from the onions that I started in the tent. I've removed that pot and sprinkled diatomaceous earth on the top layer of soil to choke out the gnats. I might try to apply a hydrogen peroxide and water mixture to the bottom of the bucket and drain pan to treat the gnats from the root end as well. We are definitely in preflower stretch now too. This will likely be the last week of growth.
EDIT: Mixed 7.5ml of 3% hydrogen peroxide to a half gallon of water. PH'd to mid 6s and then poured half of it in the drain tray to help with gnats near the roots.

After the remedies, my gnat infestation seems to be gone.
