Curling leaves.....

Pretty much every plant in my group of 20 has a single curled blade on its leaf (or 1 or 2 more). It kind of twists. So whats going on?

I'm thinking it may be because my ph lvl is around 7-8 and is too high. I'm working on lowering that. Has anyone seen this before?

I'm hoping someone can shed some light for me. If anyone is more curious just ask and i can get a pic showing what i'm talking about. Thanks in advance for the help.

Yes show a picture please, it's impossible to say what's wrong without one.

I doubt it's ph if you're growing in soil, although it depends on how good your soil is at buffering ph and how big the pot is.

Are the lateral edges of the leaves curling up or the whole leaf itself?

Hey guys, appreciate the help. I'm using coco-fiber as a medium, and using a ebb flow hydro set up. Heres some pics. Looking forward to any opinions on the matter as i want to make sure im not screwing something up. Thanks!

Could be a lot of things causing it to be honest and I'm not that 'au fait' with all hydroponics systems either, but you do need to get that ph under control if you're not growing in soil.

- Ph the water and nutrient solution to about 6.0 as GK said.
- Check the lights aren't too close, at that size HIDs should be at least 18 inches away.
- Check your ventilation and make sure the air in the growing chamber is being replaced regularly with fresh co2
- Use oscillating fans to move the air in there around
- Make sure temperatures and RH are optimum, you want about 75-85, but no higher and about 40-60 RH ideally, no higher but it can be slightly lower.

Thanks....my temp was getting to high and that may be the reason for it as well. I got Osc fan going yesterday and the room is generally cooler also because of the intake room is cooler. So if it is the temp, i worked on getting that better.

As far as PH, i got it to 7 and am working on getting it to 6.

Thanks again man, hopefully it will just stop there.

does this look like a lock-out to anyone? Do i need to flush the plants, or just make adjustments?
