Has heat or rh changed. What do they look like in natural light?

Heat stress.

Heat stress.

The temp in 78f and RH is between 35 and 50 percent

 

[420growgrow]

Right now it’s 38% RH AND 75.0 F

Regardless - the leaf is telling you the issue.

Position your thermometer at canopy level right under your light. You'll see it is hotter than what you have stated, those leaves do not lie.

It’s basicly right underneath the light and above plants. I also have another one believe reading slightly cooler. The thing is it’s been 80f most of the grow and is cooling down here so is only getting slightly cooler each day. But your right the leaves do not lie

Just because the air temp is in range dosnt mean it isnt a heat issue. IR causes surface tempa to rise and dosnt do anything to air temp. It looks like your light has a ton of red and IR.

Back your light off 6 inches

Air temps at canopy top is 84 to 86
Lazer thermometer sais canopy top is 77. If i lowered the light the air temp will not change much as i have good air circulation but the surfice temps would spike because the plants are closer to the ir.

You go by the trichromes on the buds not the sugar leaves. You have a jewelers loupe?

I have a 30-100x microscope. I thought the Trichromes on the sugar leaves was a good indication also?

No they ripen faster than buds. Always check the buds.
