Help with leaves curling under!! Check these PICS!!!

Some of the leaves have begun to curl under lenghthwise (not at the tip, but along the sides of the blades) and I don't know what's causing it! This has never happened before and I can't find another thread that explains it! Is this going to kill my plant? What should I do? The leaves aren't discolored or yellow, just curling under. I waited for the soil to be dry a couple inches from the top before I watered it. (about once every 4-5 days) so I just don't know what's wrong.

I'm just beginning flowering and now this! She big and healthy other than this garbage. Please help me save my lady!

Some pics:

leaves will roll theri margins downward to conserve moisture from too low of a humidity in the grow room. could be coupled with heat stress

^^^ werd. Plants need water too; not just nutes

Also could be low light.

Looks like they need some extra water.

put some wet hand towels in there if you dont have something for humidity already.... maybe another fan too

A fan is only going to make things worse.

Thanks, I put a couple tubs of warm water around the plant to release some water vapor into the air, but I also checked the pH of my tap water (I know tap sux, but the last couple grows were prob. free w/tap) and found it to be over 8! Would a very alkaline pH be responsible for these symptoms also? If so, I just watered like 2 days ago and the soil is still moist/dark. How can I correct the pH ASAP? I want her to recover soon to make sure I don't lose yield.

Just give it water only next time and feed with fewer nutes after that.

Maybe in the air, but def. not in the soil. They get watered plenty after drying out. I think it may be a pH problem?

8.00 is very high. just listen to TheFaux-he is dialed in on this one.

That's the thing, I don't give nutes cause they are already in the soil. I have been giving tap water but I just found out the pH of my tap is over 8.0! I got some RO distilled from the grocery store w/pH 6.2-6.8.

Think that will solve my problem? Are pH problems correctable even when the leaves are affected to this extent?

how is that gonna make things worse you dont have to put the fan on the plants just use it to circulate air....

pH is pretty easy to fix and the plants will respond to the better pH... it could be the chlorine in the water try letting the tap water sit out for a few days before you water with it
