Is This Tobacco Mosaic Virus???????????

Okay, my girls are in week 6 of Flower, so when my biggest fan leaves began yellowing, I thought it was totally normal.My book, Marijiuans Grow Basics by Jorge Cervantes, says this happens later in Flowering. Then I began to notice brown spots as well and some yellowing on otherwise nice green healthy leaves. Here are some pics. Tell me what you think, please! +rep for all responses.

No. That isnt TMV. Just late flowering deficiencies.

Looks to me like its sulfur as teh stems are turning red

Yes, theyvare getting a bit red. What would cause sulfur, is it a deficiency?

That's what I originally thought, then the paranoia hit! I'm like why did the hydro guy ask about brown spots, so I started reading posts on plant problems, but didn't find pics of how it looks in flowering plants, just vegging plants. Thanks for your input!

Well Ms , I cant tell you what caused it, though anything outside the ph ranges of 5.0-6.0 will definately contribute, but to treat for it is realatively simple. Water with 1-2 tbsp. of epsom salts. You may wish to foliar apply a 2% solution to one of the leaves and see what happens in a day or 2 as that leaf should show signs of recovery if in fact it is a sulfur deficiency.
