whay type of lights are you using and how far away are they?
what's your ph?
are you overwatering?

they're either reaching for the light or could me too much water

usually that is a temp issue..what are your cabinet temps?

 

[barnseyboy]

temp is about 87f i grow in my shed all sheeted out with 2 fans

 

[barnseyboy]

have'nt never done the ph the light is about 2 feet away from them and im feeding then 1litre each plant aday

 

[SmokeyMcSmokester]

you should drop those temps to under 80˚ if you can...and also have a fan blow fresh air on the plants..it will cool them down under the HIDs and make you stalks stronger.

thats great thanks

Werd. Get the temps like 10 degrees lower. Is ur hood air cooled? If not maybe jump on that so u can get that light closer without the upward curl. Are the tops curling and yellowing or whiting out or just curling? I would find a cheap ph test kit at the least not knowing ur ph is a no no. Lol. Otherwise post some pics start a journal and welcome to the most fucked up disfunctional family on the interwebz happy smokin
