I've never heard of them causing leaf curling.Would the trichomes do this?
My understanding is the curl results when the stomata on the underside of the leaves open wide. This increases the surface area of the bottom of the leaves, pushing them into a curl. It happens when the temperature is high, the humidity is low or both. The plant then transpires more to cool or moisten its leaves. A high transpiration rate isn't necessarily bad, though, because it can increase the growth rate of the plant. It's only likely to be a problem when excessive. This relates to vapor pressure deficit (VPD), which is a measure that combines temperature and humidity. VPD charts are available that provide VPD ranges for the life stages of the plant.The plant is happy, I have no clue why the sugar leaves cup up like that. I'm not sure it's even a bad thing. I would just like to know what causes it.

Yeah, I track my vpd. I've been in range the whole grow and my temps don't go above 80...ever.I've never heard of them causing leaf curling.
