Simple, I look for leaf edge sawing. Where leafs edges stand up. At this point your light intensity is on its very limits before becoming detrimental.Pick you brain some. Addict. How you judging lights to tops of plant and what power. Being large scale like that. . They move up and down or how u doing that.
This photonteck light is just a 600w. Yet my favourite lamp I've used yet to date. Low temps and amazing even coverage. Penetrating 10-12 inch through non defoliated canopy.
Also I still use back of hand tech. If the back of my hand is to hot at canopy then raise the light up a touch.
