The reason I have signed up here is because I have a grow at the moment and I'm experiencing some of my leaves curling upwards and some purple lines on my stems. I don't really like to diagnose my plants from Google ☺
If anybody could help me in pin pointing what this is and getting the problem fixed would be greatly appreciated.-

Whats the temperature at the top of that plant?

 

[NewbishGrower]

Between 26 and 31 degrees

Is it happening just at the top? Or the entire plant?
Mine was cooking a bit something like yours but more then what yours is showing, I had leaves starting to yellow along with the curling. If its just at the top its probably just a bit too warm up top. I moved the lights up an inch and leaned over my tallest mains so they are lower. You'll want to keep the top around 25 - 27 so if you got some parts taller then the rest of the plant try to tie them so they lean over to lower them down to the rest of the plant so you don't sacrifice light to the rest of the plant by moving the light to far up.

Yes you're right in what you say it's just near the tops. So I gather it's heat I'll move my light up abit and tie down my stretchers lol. Thank you so much. I also noticed this leaf today? Any ideas?

 

[The Dealer]

Some leaves just freak out and grow weird. It could of been covered up or pushed against something and just didn't develop. See if it happens more often but I wouldn't worry
