Cluess??? Help would be repped for sure. Thanks!

I have no idea whats going on with these guys. My thoughts are maybe wind damage, heat damage from heater for lights out temp control, PH imbalance and nute lock out, or nute overload maybe. i dont know. i feel like i have been managing plant stress very well for the last few months and today i feel like ive never touched a plant in my life.

Any help would be greatly appreciated.

it could be many things but my first thought would be a heat problem, usually a nute burn will turn the tips of the sun leaves brown.

thats what my gut seems to tell me the most. because i have this floor plug in heater that comes on at night cause it get pretty cold here in the hills. and directly behind it is a fan that blows the heat out. well the majority of the plants that are infected seem to be getting a pretty big blast from the fan that pushes the heat. but i really wanted to see what you all thought. thanks for your help

bump please.

Could be heat, but twisted leaves usually indicate a pH problem.

What's your runoff pH?

Wet

the run off ph was a little high. and so was my ppm's. but i gave them a good flush with 6.3 ph and the problem seems to have stopped. i also moved the floor heater. everythings seems to be recovering well. but i was hoping someone on here might be able to see and pinpoint a problem so i may know a little more for the future.

thanks

it looks like heat to me

that soil looks real dry to, id say a combination of thing PH/Nute burn and over heating. what the humidity in there?

stays between 30-50%

and your high temps with lights on?
and you say you got a heater in there during lights off whats the temp in there during?
also how close are the light?

temps lights on is a constant 77 degrees. (how do you make the degrees symbol?) lights off the temps are a constant 67-70 degrees. the lights are 30 inches from glass to tips of leaves.
i also have more pics of the room and more specs if you need more info on my grow journal.
thanks again for any help.

here is the link to my journal if anyone was looking for a little more detail on the room and its habits.
My 5th and largest grow attempt.

thanks again for everyones help. i will post some more pics today of how the plants are reacting to the changes made so far.

which was just moving the heater, and doing a better job of PHing the water
