Leaf curling up help plz ASAP

My leaves looking more n more fucked up I dunno if its from over feeding to heat stress...

Lil more closer up

My problem exactly to, but mine is a little more serious than this, so anyone got any idea what this is?

what kind of lights are you using and how close are they?

Yea this stuff is getting worser by the day what's ur temps?? I'm really think its heat stress, my room been a little high 85+ and I'm to scared to give full strength nutes so I don't think it nutes for me to much I dunno tho.. If mines don't start looking better by Tuesday I'm flushing and turning my hps off and just use cfl

I'm use 250w hps and it was super close like 4in from top until it got back up into the high 70's outside, I use a open window to keep room cool when the temps was in the 50's-60-'s last week

try making a foam board with a damper intake and an exhaust. one side you would open more/less dep. on temperature. downside is its a manual task

I've done plenty of manual tasks ion think one more would hurt ill try that out

My room is 20-28 Celsius and my RH is 30-40 so it could be a heat problem. i use 4 * 600 W HPS. The funny thing is only my AK47 is affecting, my WW is really healthy compering.

I have my lights around 20-30 Cm from my plants.. If you turn the ship around could you let me know what you did?

Will do.. For now its research time for 30more mins then the texans come on.!!!!!

Looks like heat and burn to me.

So it's heat stress and nute burn?? So I should flush and keep my hps off till it become cold again which could be tomorrow.... I hate Texas bi polar weather

The burn is really light. I would just back off the nutes a bit and try to move the light furthur away.

That is being caused by heat. The plant uses K against heat stress so the plants are using up their K and this is what happens. It can happen very quikly. Espcially in flower.

It did happen VERY quickly lol I mist them down last night when lights went off and flush really good this morning after that it started smelling like grass... Like front yard lawn grass... I just smelt them and the smell is coming back and it look like that mist last night brought orange hairs out lol

Yeah so my mystery is over, it was heat stress that caused it to behave like that... my timers were busted on 2 of my 4 lights, shit timers for like 3 bucks. So all is well for now but I need to keep an eye on my plants because i think the stress have slowed down the flowering phase...

Can someone comfier that the stress can stop the flowering phase or really slow it down if it doesn't get some rest in the "night"
