Question about relative humidity

[Hassan420]

Hello ! I have 27% RH usually. I have leaf edges curling upwards is it because of the very low humidity ? Temperature is 25-26 under the light.

27% is pretty low. You can get away with lower rH if you run your temps on the cool side, but your best bet is to get that rH up. Get yourself a humidifier.

Edit: Does the leaf problems come from the very low RH% ?
