Viparspectra p1000

I’ve been trying to use 2 viparspectra p1000 in a 4x4 tent unsuccessfully. Been having signs of heat stress on every plant I had under them. They were hung catty corner at about 50% reduced lights to 35%, still heat stress. Took one light out and hung the other straight overhead at 60%, still stress, now it’s at 30% about 3.5’ above canopy, this is the result but I’m unsure why.

I'm still a newbie, but to me it looks more like nute burn. Hopefully someone more experienced can confirm

Definitely not a light issue

what do your roots look like?

it’s not root problem did have a little heavy nutrients a couple weeks. Let me add this next pic, you can see the stress I’m talking about, the serrations on the leaves are raised way to much, which i thought was indicative of heat/light stress. The temp 5” from canopy is 77 degrees.
