Reason I ask because my leaf temps and canopy temps do not make sense

I'm using a 600w how in a 4x4 tent 2m tall

I shade my thermometre with a piece of cardboard and cover that with foil, at canopy level , level with my plant tips on the wall of the tent I get a air reading of 75-77fmax doesn't go over 77f Humidity is 50-55%
Then
I have another thermometre at pot level on top of the pots this reads 67.8-69f

When my csnopy reads about 75 my lead temps read 68-73f

Anyone have Any ideas whats,
going on?

Maybe u shouod keep the temp at the pots 75-77?

I also have a thermometre Under the light not shaded its mwsureing radiant heay this reads 77-80 sometimes 81

Leaf temps under LEDs are always low.

Hence LED growers running rooms a few degrees warmer to compensate.

Is there an issue with the plants or are you just overthinking it?

Sorry I was ment to say 600w hps I have ,
I'm deffo overthinking I get it bad last few years it's a problem that's for sure haha
I have also been playing where I place my oscillating fan if I blow my fa across my canopy so it blows air between the plant tops and the light thebthat air blows at my thermometre on the wall ,
Or if I move my fan to blow at a wall not directly at my themrometre in then get quit a diffrent reading, it's passive intake pot level is about 67.7-70 So I'm thinking this cold air rising is also messing readings aswell as fan position,

Do you think is a good idea to blow fans at themrometre for better readings

If your plants are happy stay the course. If unhappy, post pics for problem solving.

I run fans above the canopy and around the pots, trying to create a gentle vortex.

If you think your leaf temps are low under the HPS, raise the average ambient by 2 degrees F.

You rub pure led
What temps do you run
What setting do you put your fan controller to 28c thst gives me a air temp of 82-82f

But I also been told 80-82 air temp
For this I need my fan set to 26.5c

Do you mesure leaf temps

Again I been told 2 diffrent number
75-77
And
80-85 On site below
