I’ve been seeing Temps being almost too low for canopy with led… without the ir a hid will put out leaf Temps are almost too low, so I need to grab a ir thermometer to check actual leaf temps

I’d bring your ph up to 6.5 I don’t run led but gavida 1000 hps . I do feed around 700 ppm using pro mix steady feeding checking run off out will tell you when to flush . I’ll maybe do 3 feeds then a water depending how the plants look.
Make sure you always get plenty of run off pro mix is known to build up nutrients into the high 1500 plus range .
Pushing plants harder should mean more nutrient I run c02 @ 1000 till the last couple weeks then cut back to 600.
Are you extracting the room at lights out?
Temp you should be fine overlighting definitely a possibility try cranking the light back and raise it are your leaves praying?
Leaf temp is 3 degree cooler than room temp.

I have dialed light back about 80 ppfd from 400 to 320… with hp cc you have to run off every time or like u said it will build up… so what’s optimal leaf temp then… I’m guessing 82 ??
Dependent on your room temp 3 degree isn’t optimal but close to not cause trouble . Do you have vpd chart your trying to follow?
I’m ignoring vpd until I can know the true leaf Temps because of the led difference in heat and ir

I have never done a breakdown of AN.
If you post the back labels I’ll try to decipher to ppm.
A few well known mix breakdowns.

Should I be running closer to 6.5 vs 6.2 in my Octos
I’ve only grew 1 plant in my octopot and I believe I was any where between 6.3 / 6.6 I was dealing with extreme heat last summer. Water temps change ph a fair bit I’ve found.
