Spotting/Mottling- Mosaic Virus?!?!

I have one plant that looks like it's bleeding out. The green seems to be less so and there are spots/mottling. Like it's being sucked of its green color but I see absolutely no signs of bugs (no eggs or webs, doesn't look eaten). I reeat- NO SIGN OF BUGS. The leaves are curling a bit.

Anybody venture a guess what this is?? Please, I need to know whether to quarantine her (if she is contagious). This looks like a cucumber mosaic virus or tabacco mosaic virus, but I've read that neither of those are known to affect marijuana.

I don't wanna risk jeopardizing my whole crop. Please help!

Pick up some Garden Safe3 from home depot. Its in a green spray bottle. safe for use on vegetables. Use as directed on the label. Also check your humidity. Good luck.

...the discoloration resembles a Magnesium issure, IMO. Are you watching your pH balance? I would transplant into new soil. What is your water source? Here is a link with similar looking plants to analyze, search the catagories >>>> http://www.ganjaguerrilla.net/Album11.htm
