Leaves folding upward along the length

Plants are doing great otherwise. Possibly slight nitrogen deficiency because some of the lower fan leaves are beginning to yellow but I'm not TOO worried about that since they are starting to flower (and need to be trimmed).

Outdoor
GH FloraDuo series (was using 3 part for very beginning of grow but have been on the Duo for weeks now)
Hydro, in netpots
Recirculating reservoir
Waters for 10 min every hour. Takes about a minute or so for the pump to fill the line then two steady drippers per bucket.

The leaves have never done this before.... if they were just reaching towards the light I would expect the leaves to be growing upward more rather than out like these are, no?

I've been thinking about the overwatering because 2 of my 8 plants on this reservoir/nutrients are somewhat wilted (just doesn't look like they are absolutely loving life like sometimes), but I think it's hard to do with hydroton in netpots. And I've been running this watering schedule for many weeks without issue.

from what ive read this is a sign of heat stress, my outdoor plants were doing this a few weeks ago but then returned to normal nothing to fear,

its heat stress, this is what happens just before they burn. either they are low on water... or if they do have water already; then its salt build up

Those are some nice looking plants. But it looks like to much heat and not enough humidity. And the plant is trying to save H2O. Are you haveing a freaky hot summer like a lot of people are this year? If this is the issue, then try and lower the heat, raise the humidity, and mist the plant when lights go out. But do not go nuts with the misting. I hardly ever mist my plants. But if the plant is having heat issues during the days, then some moisture at night to evaperate off and cool the the leafs down plus a little drink might really help.

Those leafs are a uniform green. No brown spots. Not red or golden veins. No fried tips. If those leafs were laying more flat, I would say that is one happy plant.

It's been 70s-80s here all summer so heat stress doesn't really make much sense. Shouldn't be low on water, they drip every hour for about 10 minutes. Salt buildup is a possibility though.

Not a particularly hot summer here, 70s and 80s mostly.

usually that means that they are over heated.but being that its outside its probably just soaking up some rays :) now today it was 105 degrees where i live so if you live where it was hot today than that explains it.she will be fine
