There's no nute burn on this one. You have nute burn in some of those pics — the ones with yellow tipped leaves.

Have you used auto pots with soil before?

 

[Aqua Man]

Know what your leaf temp is?

Whats the humidity?

May inspect the rootzone for pests also

Hay mate

Leaf temps are in the video
I locked myself in my tent and zipped it up and then took the leaf temp video, not sure if my gun is accurit if had a few they all read diffrent

Also pics below show floor air temp and a probe in my soil

And other pics of symptoms where also taken today

I keep room fat temp 80-82 my rhino fan speed/temp controller is set to 26.5c that's 80f so or keeps room 80-82f night temp 75f min

Just turned my auto pot water butt off might water plain water for 2 days then feed at 1.2,
I can't mesure e.c run off in soil can I it don't really drain much like coco

If also got 2 of these in my tent blowing the hot air from above down to the canopy only used them on this and another grow they new to me

 

[Ph 007]

And where is the leaf temps in by veg T5 CFL light room the temps 75-77
When I took leaf temps of this room the air temp was 76.5f in video below so in guess my IR Gun is accurit I think?

And 1 hour later I took led leaf temps Again but this time with them air defuser turned off

I'm debating on moveing my day time tube heaters to the floor the ate above canopy at moment

 

[Aqua Man]

Yeah move them to the floor. Take leaf temp from 12-14 inches away.

Your sensor placement is key to measure air temp and humidity.

Temp should be canopy height shielded from the lights.

You humidity should be just above canopy.

Your air movement is most important under and through the canopy. So id place one of thise fans in the middle of the tent drawing air up to the top and circulating it back don the sides under and through the canopy back to the middle and up… if that makes sense

 

[Ph 007]

I left them air defusers off for like 30 mins to a hour but I put oscillating fans on blwoing across the top of canopy between the lights and plants and just checked leaf temp again I did also tuen idel down and humidyy got tad high end, air canopy temp was 81.3f humidity was 66% and leaf temp read 79-81

if

turned my fan controller down was keeping room 80-82
Now I'm trying 78-80 for a hour .

So you need to shade sensors and themors from the led light?

I did in the past they looked good but wearnt really shaded well , I though led didn't matter I have noticed shading it does give slight diffrent readings but I though everyone saying 80-82 for led was not shading them so I just stick with not shading them lol God man I man it's all be3n head work last 2 years :(

Here is a grow from last year led coco shades well sorta and the looked great theb went bad later on not that bad run still grew and yielder good

So you reckon shade them from the led is it?

Yeah shade them and validate the accuracy. Your olants looks great man and trying to get perfect is a lot of work for little gain but…. That said i applaud your drive to do so, its gets tiring as hell but separates the men from the boys sorta speak

Remember evaporation is cooling to a plant and its roots… typically you will see media temps about 5f cooler than room temps and that outs you in a great spot where you are

I'm not 100% sure what you mean bro
I could so this in pic below 2 extractor 4" they will bring top of tent air down to pots and the other extractor will suck air from the pots up to top of tent or is that not what you mean

Plan's/blueprint below, not drawn to scale ;)
