what this ?!?!?

found this two days ago, flushed the plants and now i just added a little grow nutes at about half strength

From looking at a 3rd of two fingers of one leaf it looks to me like over feeding, over watering stress - assuming the plant is in veg, but if its in flowering then depending on how long into flowering it could well be normal.

To help people determine what the prob is can you supply more info.

- Strain
- Lighting
- Air
- Soil/Hydro/some other hybrid method you invented yourself
- vegging or budding
- how old is the plant
- what are you feeding it
- size of the pot

stuff like that might help you get some more replies.

strain ice
lighting 400 watt metal halide
air? co2 tank and regulator
aeroponics with oxygen tank for a nice boost here and there
vegg
5 weeks old
feeding gh trio
30 gallon res

Ok, thanks for that. What are the PPMs of your co2 and for how long do you feed co2 when lights are on?

While on that subject, what is the ppms of your nutrient solution

Nute burn with over watering are some possibilities.
The brown on the leaves edges indicate nute burn~
Drooping maybe caused from not enough air to the roots~

yup... it's nute burn...

The other possibility though is that over use of co2 will look exactly the same as that. Which is why I am asking for more information from this grower.

PPM of the nutrient and PPM of the co2 as well as the length of time the co2 is dosing the air.

its fine now plant looks good my ppm is around 1000 right now and we're doing good, co2 was being used for 1 hour at lights on, then 15on 15 off untill an hour before lights out, and i forget the setting but i know its right its like 30 psi and i have it set to .4 on the solenoid valve or whatever
