Against the wall with plants between the light source and the meter?
Can't believe the led isn't dropping off faster than that.
Moved the plants out of the way, unshaded, but my led panel is large 80cm x 80cm with most of the bulbs(20) going around the outside.
spotlight reflectors cause the focused light on the canopy narrow and strong

About time for an update, day 42 (12/12), The canopy all looks the same, 438w of led covers about 1.1m x 1.3m, and the 600w HPS is covering 1.2 x 0.7m, there is some overlap between the lights but still.

The far-right side under the 600w HPS

and a center view with the lights on, see the difference in colour but the canopy look identical, leaves have curled a little under the HPS

Here is a side view of one of the plants, this plant is just over 2ft tall and 2ft wide in a 29ltr pot, under the led
