OK, this is a defficiency, but it is not because the soil is lacking anything.
So I'll give you a little lesson.

90% of all defficiencies are caused by either over or underwatering.
What happens is that with either of these watering problems actually kills or sickens your root system.
When this happens, the roots can no longer assimilate the nutrients contained in the soil.
Thus, signs of defficiencies.

At this point of flowering, which like fall tree leaves, are a colorful act of death.
You are almost done with this plant so just do everything the same and finish her off.
If you start adding anything to try and fix her you will end up with nasty tasting bud.

Please feel free at any time to post photos on my advice thread and ask there.
This is a common problem and it educates many blades, everytime it comes up.

Your buds look fine and tasty.
Peace Bro.

PS, Easy on the 'Sir' crap:D

Thanx so much for your quick reply SG1. Ill just keep on trucking with my feeding schedule. Again, Thanx so much!

As a precaution, I would flip that leaf over and check for mites. It looks like mite damage imho.
