to be honest it looks alot ike an iron def, but its a little different, might be an iron def....hows the ph?

i really really doubt its tmv or another mosaic virus, as im sure thats what you were thinking

[Maj.Cottonmouth]

It is exactly what I was thinking. pH has been 5.5 to 5.9 max, I usually keep it between 5.6 and 5.8.

ya well although it doesnt look like the anormal iron def because it doesnt start at the base of the leaves, it still looks more like iron def thn anything else i can think of...although i must say ive never seen a lef exactly like this, but to me i would have to go with iron

Thanks man.

[stihgnobevoli]

i would say it's environmental based on the location of the damages. whats on that side of the plant? is it closer to the light on that side? did you foliar spray recently? deficiencies don't usually stick to one side of a plant.

Give K and epsom. Has plenty N needs K.

looks like K lockout , you may soon start to see dead necrotic areas.

If it was Mosaic you would have leaf bend . You would see some leafs bend to one side and the other side look like it was eaten away. You have some form of nute deff. My guess would be Potash though rare it could be and you can't really get to much K. It could be a Micro nute as suggested in prior post. I would try a complete nute with extra K. And maybe some epsom salt foliar.
