Leaf Curl

[tribeca]

I have a problem with my leaves curling up.I'm growing schrom from clone using promix and Head Formula.I water when the pot gets super light.Here is a pic.I have read plenty of advice but no one has said that heat,nutes lockout was the problem and was corrected.Im growing in a greenhouse but this clone was grown here last year with no problems.

Looks like heat stress to me, but there could be a few reasons. I'd really have to know exactly what you did. You'll just have to go with your gut. :angel

fed as usual and watered as usual.Nothing out of the norm.Water quality might play a factor but who knows.I will give her str8 water and if she yellows up I will give her a light balance feed.

What a difference that hour must have made.

Surely I have limited space and have no time to play with guesting or assuming..hence the reason i asked for help.Her replacement is in and doing great.Thanks for your limited time and help.I assume it was growers error so now I'll check everything from runoff to temperature.Did a nice cleaning after I trashed her and everything is looking healthy.Using coco as I will be able to better track my progress as well as catch nute problems or ph.Thanks again, now I'm off to the races.

i know for a fact that leafs do this when they seek heat

The leaf curl is caused by excess salt locking moisture in the leaf and making it impossible for the leaf to transpire properly when it needed to. A simple flush with dechlorinated water would have accelerated unlocking that salt, and could have saved the poor girl's life. But if you've got extra ladies around, I guess you do what you feel you have to do. You could have taken her out, found a quiet spot and set her free... Oh well, can't save 'em all!
