Took the saucer and riser out from under the tallest plant and stacked it under the shortest plant to help level the canopy. Probably should have done that a long time ago. Not sure why it didn't really cross my mind. Maybe it's because I'm used to having a dedicated light for each plant that I would run at different heights rather than one big lamp for the tent. Adjusted the light height so that the tallest cola is getting 65,000 lux and the rest of canopy is around 50,000. Will give that a try.
Some of my plants stretched more than the others and hopefully I have 4 separate lights which allows to level things up. Can't wait for the next weeks as many of us will soon harvest
