k so my leafs are starting to curl in and down any idea why? could it be cause of cold temps? high humidity?

it seems that it only does this when dark. when lights are off the temp is from 60 to 70....when on the room is around 80. the humidity when on is around 50% and when the lights turn off (which i just checked was kinda high 70%. i know when the lights are on everything is good temps and humidity. last i checked sat the ph was 6.5. ill check again tomorrow. any ideas why this is happenin?

Just as some more info when i walked in there this morning the leafs were lookin fine. There was a couple leafs that were curling under.... but tonight when i checked in there an hr after the lights went off thats when there were more leafs curling.....

my guess is heat stress how close are the lamps to the trees?

Guarantee to you if you flush and cut back on the nutes you wont have any new growth curling.

Look familiar?

nah cant be heat stress. temps dont get to high and the lights are not close to them enough to burn them...

fyi it is on its 20th day of flowering....

If it were heat stress they would curl up and be slightly crispy.




Classic sign of overwatering. Do you let it dry out between waterings?

dont think its over watering they are watered 4 times in a 24 hr period. so every 6 hrs they are watered for 15 mins.... if it were over watered it would have started doin this in veg.

Lack of light and cold are the only times I have seem this happen with my plants... But I always let my plants dry out and I'm not in soil. Mr. Ganja knows whats up so...... listen to him.

I wasn't aware it wasn't in soil.

i was thinking the coldness might be it. its in flowerin so its getting 12 on 12 off. maybe i should get a heater mat to keep the roots nice and warm during the night?

Yeah dude and let those babies dry out good before watering again... just don't let them dry out extremely unevenly. If they are wet on the bottom and really dry on top (roots drying out on top) wet the top of the medium a little bit bit to keep it even. you want a nice solid root structure. go get yourself some B complex also Nutra boost is good stuff. anyway good luck to you!

As I always say this is JUST MY OPINION but I do have some good results myself :wink: __________________

that dont look like burn, im thinking some kind of stress related, rather heat fluctuations, water stress, ( hard water), in soil you get that to as well as hydro.

im thinking it could be because of the temp drop when the lights are off... good thing the cold weather is about to start gettin warm.....
