Molybdenum deficiencies occur mainly on acid soils
throughout the coastal areas and on much of the
Southern Tablelands of New South Wales. Parts of the Central Tablelands and Northern Tablelands are
also deficient in molybdenum, and molybdenum
responses have been obtained in crops in the
Murrumbidgee irrigation areas

that would be the type of situation i would think

With the dull bluish/purplish leaf color of the first two pictures I would say it appears more like a Phosphorus deficiency, but if your temps are getting to 50 degrees F. or lower that could be the cause. When temperatures get that low it inhibits the intake of Phosphorus.

Good info all. It does make me wonder how a plant could have a molybdenum deficiency. Dj had a good post on the topic. I also wondered about a phosphorus deficiency as well, which was stated by brick top. Not sure which one it would be though. I'm gonna take a crack at the molybdenum, from the pics I've seen it looks exactly the same. Now to try and find a cure for the situation. Does anyone have any ideas as to what has a good source of molybdenum?

unless your growing outdoors in New South Wales...then molybdenum isn't what your problem is

i'd say cold temps and lack of P. ;)

could even be strain related. :)

ditto...id say the same thing....but ask why are you cutting,other then some crimping,healthy leaves off a young plant.leave those babies on till yeah are dead and not using any energy.but i was wandering if they are in cramped conditions...i've had leaves do that growing in small grow area and they crimp like that when they was growing right against the wall of my grow area.not to say there isn't another issue since the stems are purplish though.
