Do plants sleep,or just get tried????

[i want a green thumb]

The Grow Room Is 2hx 1.2x 2.3
Lights 1x 600watt HPS . 1X400watt HPS Are on 18 hours from 6 am till midnite, they are set at 30 and 50 cms
6" exhaust fan was on 15 minutes on 15 off. now on 24/7 a touch of WPM in the other room
18" oscillating fan
temps high of 30 and lows of 18 celsius
Plants 11 Autos , 6 at just on 40 days AK47s and White LSD. 5 other at 28 days all AJ Kush
All the plants are on a Canna A+b, Diet 20 mls to 15 lts of 5.5 to 6.5 Calmag at 15mls to 15 lts and cannazym at 15 mls once a week. water feed every other day ,just ph water the next .
there was an over feeding a week ago , they got a full strength bucket of feed after a mix up,it did muck them up. lots of flushing.
So now I have ALL 11 PLANTS doing this. IT starts about 3 pm in the after noon . I can see the leafs,stems and tops all start to roll up, twist, then go a pale shade of yellow . Some plants don't show much sign ,some very much so after about 2 hours they look like this

6 am the next day they look fine again

they are all growing very well 4 to 6 cm per 24 hours, some a little pale.
This has been happening for 4 days that I have really noticed
So can someone tell me are the girls just all partied out ,or am I missing something

I always have a dark period. As from what I see it brings more resin/trich production earlier on. They could be a bit hot them cool down. Everything is fine... Plants droop after being watered the perk up again. Mine always do. Almost instantly get droopy for a few then perk up. They'll do it in the dark too then "wake up". Long winded point lol its all good

any timelapse vid ive seen the leaves flap up and down.i assumed that was lights on/off and feeds.
and if you go to far in one direction or the other with watering they do the same.
