Severe curling under of leaves...HELP!!

When I put the plants into the extra flower room I changed the light cycle to 18hrs light for a week or so because I still need to clone off of them... So I havent even really changed there light cycle...Your plants look great! the curling on your leaves doesnt even seem to be a problem...But it's all relative. Some would argue this, but I would remove some of the large fan leaves towards the top of your plants to allow more light penitration to some of the other bud sites(under the leaves). Your call dude...
If I new how to post pics I would post my plants today, but I'm to new to this site..?? How simple is it??

Looks like someone foliar sprayed pure salt on them. They are going bad from the top down, and I am sorry but I have to disagree with the guy that states they look great. Unless you spend a lot of time getting them completely healthy again prior to flowering you can kiss yield and quality goodbye brother. I would keep them as an option for the next grow if they come around. For now I would start some new beans as backup.
I know you state that they were not feed in a while, but something is causing the n overdose on these girls. Changing environment can cetainly affect nutrient uptake, so flush, flush and take readings (not very useful in soil though) of run-off, maintain a consistent environment, wait until overall appearance 'lightens' a bit before feeding them half strength again.

Interesting stuff, Im 2 1/2 weeks into flower also growing Ak48 and noticed some (3-4) of the larger fan leaves on both plants are curling at the tip downward. The plants look healthy as can be except for this issue. Maybe I missed it but how far along are your plants? Definitely gonna keep an eye on this.
Just for comparison here is mine.View attachment 1415568View attachment 1415576View attachment 1415578

Too much nitrogen, not enough PK. The leaf curl and the intense dark green color are dead giveaways.

Unity, just to clarify I personally think that echonc isnt in bad shape, but I agree that ramie808 might as well start over...
Is that what you are saying...?

Cheers Parker, I'm saying that he should expect a serious delay before he can flower these. For me 2 weeks would be a serious delay for example. I would get me some new clones if possible where he lives and nurse these back for the next run. If he has got time then it doesn't matter that much and he can just see if they come around.

I would agree...Do you (unity) have any ideas what might be going on with my garden??? I have a post on page 4 and top of 5...I was hopeing the plants would adjust to the new environment,but are not...
Any advice would be appreciated by anyone!
Thx
