I had to raise the lamp to the highest point I can without obstructing the lamp's exhaust. I have 20 inches with the majority of the canopy, but the extra tall branches are at 16.5 inches from the light. The space between these branches & lamp doesn't seem to cause issues.
Other than that, nothing really out of the ordinary this week. I simply kept feeding the mid-bloom formula while keeping an eye out for fan leaves that grow too large.
