drooping leave problem! help

I am growing twelve plants on an 18 site aeroponics table. During the last 4 hours of night and all of day time they are beautiful. When I first turn the lights off they tend to droop pretty bad for about 8 hours. I have troubleshot EVERYTHING and cannot seem to find what is causing this.

I talked to the guy at the grow shop who uses the same table and he claims to have never heard of these symptoms while everything else checks up.

I run a calculated neut program with advanced neutrients. I've had a fan blowing on them since day one with good intake and outake air. I run the room at 50% humidity. I keep the PH at 6.0. My ppm stays around 1000. I pump Co2 with an organic bucket.I bloom with a 1000w hps in a 4x6 grow tent.

SOMEONE PLEASE HELP ME THIS IS DRIVING ME INSANE! thanks

Get the humidity down.
Proboly causing it.

i've always known 50% to be ideal. My room was down to 28% so I kicked it up to 50% and this problem was consistent both times.

Your plants are sleeping, leave them alone.

What happens at night is the plants rest, they do that by moving moisture in the leaves to the root ball, this cause the leaves to lose some of the stiffness. Very common and I would find a new answer person who knows a little about plant biology.

That is why they recommend you harvest your plants just before lights on as there is less moisture/nutrient in the above ground part of the plant.

very helpful woodsmaneh..thank you. I had thought the same thing so this makes me feel comfortable.
