Leaves dying during Budding Q

Hello,

I've got these plants. Next Monday they'll be 8 Weeks. I wanted to let them go longer.

As you can see, the leaves on the large one are pretty fried off for some reason.

It's in Fox Farm and I only give it half strength ferts once every 9-12 days or so. Molasses, Kool-Bloom and Tiger Bloom.

It's usually pretty dry before I give it water. It starts "Wet" on the meter. I don't water again until it's down to 2 or so.

I was thinking heat stress so the other day I raised the light. At the top of the buds it's like 92 or so now.

But then as you can see it seems to have begun on the little ones.

Perhaps once all the leaves are gone it's ready????

Any comments are fine.

Thanks.

Oh man ! 92 degrees at the canopy is bad,real bad,you got a serious heat issue i'd say.

yeah dude , thats hot hot hot! get a fan on that asap.

Thanks.

What about 89F? Look at that pic!

I reconfigured raising the 600W a few inches while removing the T5.

Less Lumens.

From Cool-Tube tangent to tippy-top of bud is about 13". The bottom buds aren't getting Super-Lumenized.

89F.....
