Odd Curling (Exsperianced Grower)

Curling downword leaves? Never seen this one before not to worried about it, je wondering if anyone has any thoughts. I have tried flushing plants, have tried using more than usual nutes and less, with no affects. These leaves only occur at the middle of the plant, as the upper and lower are not affected are are healthy. Have tried giving more light and less light to the leaves with yet again no affect. Been flowering for about 5 weeks, and veg for about 4 weeks before hand. Pics below.

how ph or humidity
thoose could be it. It looks like plant is having problems with getting rid of water.is the medium too wet I'd dry.

yeah,,, how often do you water,, looks to me like it could be overwatering,, ...................................................

Unable to check check PH, i water about a lil more than a quarter gallon every 3-4 days, medium is usualy at a dry "looking state" but i stick my finger down into the soil to check for compleate driness or when the plant starts to look depressed is when i water. I have a humidfier going with the 12/12, and room temp stay around 80-90, as theres nothing i can do to lower temps at the moment. But it dosent looks heat stressed.

Maybe to humid

Mine did that when the soil was to rich. I've also seen it when the plant gets to hot. I overheated mine and they did that, they continue to look like that but the plant is healthy........

The leaves of this plant did that when it got to hot and even after I fixed the heat issue the leaves never straightened out...

i see, welp, that would be more than likly the issue here then, i guess im just gonna do with some ugly leaves untill i can figure out how to work out this heat issue. Thx for the input guys.

Ive had that before it was due to low humidity and heat. Once it happens the leaves dont un curl. 80-90 seems a bit hot. I grow in a cabinet and its like 80 degrees at the light and my root temp is 60 degrees

I think it looks normal for a satavia. At least it looks like the ones I had in my first grow. They seem to shed different than the indica dominant strains. That is a guess based on my limited experience. VV
