The way I read it you have to be between 70-75% RH at 79°
Quick question y'all since my auto thread is too quiet. Can I use my granulated Spa-Up to raise the pH of my nute water? I'd dissolve it in distilled water first and add it in small increments, because the Tiger Bloom is pretty acidic and gets the pH down near 6.0 at full dose. Here is the bottle:
I'm not sure if that's an old graph or just strictly for HID lights? Here's a calculator I've been using along with a ton of other people. It allows you to adjust for air/leaf temp at the top left. I use an IR laser thermometer gun off amazon (20$) to take leaf temps. Then input difference and go from there. Being able to change that variable is HUGE as LED doesn't heat up the plant material nearly as much. Which is why you can run higher temps and lower RH in an LED grow.

Lol you should be in the right range to nail vpd , personally I find my plants love high temps under led so I try to be 78 to 80 and they seem really happy with 60 to 70 percent humidity right now! I think watching and listening to what your plants are telling you is more important then what the graph says
Up to 80 degrees is fine just keep things close to optimum and your golden
Give it another 24 hours in the towel, my big tent is 78f and 72% humidity
