Most likely it’s wind burn and low humidity isn’t helping.

How do I increase the humidity?
I have a small bowl of water in there near the heater.
Try hanging a wet towel on the side of the tent. Point a fan at it.

Sounds like a plan. I'll have to figure out how to hang it in there.
Or take a 5 gallon bucket of water and hang a small towel half in and half out. Again use a fan to evaporate the water.

I have a tiny grow space in a retrofitted cheapo armoire. I filled a glass jar with water and have a sponge in it sticking out. The fan is pointed at it.
Hopefully that will help. RH was 34% up top, this should hopefully get it above 40%.
How did it work out?

When the lights come back on I'll let you know. Lights are on during the night.
Ok cool I’ll be around.

Half the jar of water had evaporated, RH still around 35%. I have reduced exhaust fan speed to low. It's a powerful exhaust fan. Had bad heat issues in the past.
The I take is cold and dry since it's a basement setup. (60°F)
Ugh, maybe my hygrometer/thermometer is bunk? Leaves still curled .
Is your fan pointed at the plants?

Not anymore. I changed that last night.
When I reduced the exhaust fan speed, RH shot up to 45%
Temps stable at ~76°F
Wind can do that, 45% is good.

Thanks to Pennywise I believe the low humidity issue may be mitigated.
Here's some pics. There is still some curl, but the leaves aren't as stuff/crispy anymore.
Temp is between 75°F and 76°F and RH is about 45% below the canopy. It's about 35% RH above the canopy.

Hopefully they look even better tomorrow

Pics from last night are incoming. The curl isn't going away, so it may be genetics or my exhaust fan is too powerful.

Can you raise your humidity?

When the exhaust fan is off, humidity raises quickly, but so will the heat.
Should I raise humidity with lights off instead? I can turn my exhaust fan off then.
