Its called 'cupping' or 'taco-ing'. The plants way of telling you to raise your lights.

Damn Mexico - we need a taco tax

ummm
it could be lights to close but,
id say your magnesium def

do I see a crispy fan leaf in the corner?

a picture of the entire plant would help

you might need some epsom salt.... 1/4 tsp per gallon is common

here is a copy of a picture from a MJ trouble shooting guide from

Plant Abuse Chart and Photos by Nietzsche

see the taco leaf

if your only showing it at the very very top and your lights are close and the plant is bleaching out then your lights are to close

but if your getting taco leaf 8" down (or more) from the top then its magnesium def

a picture of the entire plant would be good

ya, im pretty sure your mag def

if you post your nute info I can take a look and see if your getting enough magnesium or possibly to much calcium

The plant was overwatered and seemed to get Nutrient lockout - hoping to get it back to normal before too much damage is done
