what does slightly curling under and in on otherwise healthy looking leaves mean?

Barneys Farm Critical Kush in hempy 13litre 2-1 perl/verm. 5.8ph dm gold 50%. 400w mh. Temps were improved last night to 26c /78f after raising light to 11 inches. Flushed with straight ph 5.8 water today.

Quit watering it for a sec, bet you just flooded her a bit

Looks like minor heat stress. You mentioned that temps were improved. What were they before?

Pretty sure tacoing is more indicative of heat than curl down, but anything is possible...

I only say that because I have had similar looking curling of the top new growth when it gets just a little too close to the HPS. Also, doesn't over watering typically show in the older growth first and involve wilting? And in hempy is it possible to really over water? I wouldn't know really as I grow DWC, but I thought the whole point of hempy was to take the guesswork out of watering by utilizing a media that retains little water, thus preventing under/over watering. I could be wrong.

only water when needed, dip your finger into the soil down to knuckle if its moist under there it doesnt need water yet.
dont get too worried as it is what it is a weed, its pretty resiliant.
i recall a time when i used to turn lights on and all my girld drooped like this, turned out they just hadnt woken properly yet.
good luck.

I think my 2-1 perlite/vermiculite mix retains some moisture cus of the high vermiculite content so I think I'll not water for a couple days , I'm sure all the roots are in the res. I moved the light away a bit when I noticed they weren't looking so good. The temps were up to 29c/84f at times.

Irrelevent. He's growing soiless. And my plants never look droopy when the lights come on. Must be a soil thing.

Ya but if he just took the pic after having flushed might still be a lil soaked, nothimg damging should go away like 1 or 2 hours after flushing it. I c my plants leaves droop a lil after increasing my water amount, then they get used to taking that much and all is good. like i said it could be what you are talking bout cus i have seen stranger with weed, on sexond thought could very well be what your talking about since i do not grow with hid, easy moneys on water tho if u ask me.

Ok will do mate. Yeah Ive noticed plants do that during dark but these don't move at all when the light goes on.

Prob just stressing too much. I'll just try to keep the temps down and water more infrequently. Thanks for replies
