Having your 360W Square 3 at a slight angle shouldn't hurt much, especially since you’re already running panel LEDs for that extra side coverage. The main thing with angled lights is that it can create "hot spots" or uneven light distribution across the canopy, so just keep an eye on the plants closest to the tilted side to make sure they aren't getting too much intensity while the others get shaded. If your coverage still feels even and the plants are reaching up happily, you’re likely good to go, but usually, keeping it flat gives the most consistent PAR levels across the board!
