What’s the best leaf temp when using COB LEDs?

Hello,

I’ve been trying to figure out the desired leaf temp to maximize growth in Veg while giving enough light in Flower while still maintaining good size colas but not getting foxtailing or airy buds ?

This is what I’m thinking for my ne t run . Feedback is always appreciated!

In Veg: If I skip CO2, 82-84F for maximum growth (Metabolism) with 600 micromoles per second or about 37.5 DLI.

In Flower: 82-84F at 1000 uum (micro-moles per second) for a DLI of ~42 and with CO2 at 1200-1500ppm, I was thinking I could push 1400-1500 uum or DLI of 50-62.5,

Here’s where I’m not sure. Normally at that CO2 range I’ve read guys shooting for 88-95F air temps but with LEDs we run about the same temp or +1-1.5f above ambient air temp. So... I was wondering what leaf temps should I shoot for?

I’ll be lowering my air temps, light intensity, and CO2 around week 4 to preserve terpines and avoid airy buds (do those reasons sound about right?). I’m still new to this and trying to put together everything I’ve read. Feedback is greatly appreciated before I try this on my next 4 ladies. Once I figure this out, the fun part is going to be trying to keep the humidity in the right rangefor those temps ‍♂

Anyways, does this sound correct or am I screwing the pooch with my understanding on how to optimize growth and have nice large dense buds?

Any feedback would be appreciated. :)
