Usually means your light is to intense or the heat how close are your lights ?

8 and half inches I am usint 2 x 105w cfls

105w actual ?

That is called taco-ing, and is from too much heat.

105W (525W equivalent) Continuous Light Bulb, ok thanks alot I'll keep an eye on my temps

cc2012 · Apr 1, 2014

yeah could be Heat?

How close is your Light, what Temps are you getting in GR?

Peace

There 8 and half inches from the tops of the plants and temps are round 31-33ºc

That very well could be the problem. Try to keep temps under 27C at all times.

Thanks everyone I'll get the temps down and see how they react :weed:

Just wondered if you solved you leaves problem?
I currently have the same problem with one of my plants?
Do you try raising your light up slightly?

In my own experience, not only will hi temps/too intense light cause that, but your humidity being too low will, too. Combine low humidity with hi temps, definitely will taco your leaves!

I need more fans, my temps are staying around 30c.
But my plants have improved, with light being raised up.

If your grow room or tent is near a window you could run some ducting from the window blowing the cold air on your lights a mate of mine had this set up and he never had a heat issue

Yep am getting things in control just about am under 30c now and plants are perking up even the canoe leaves one.
I do have a window right next to grow tent, so am considering an inline fan/ducting from the window.
I've also raised my lights a fair amount and I think that has made a difference.
