I've used the RNA Pro with good results, but this was started on vegetative clones rather than late flower.

IMO you have an insect vectored mosaic virus. Even the signs of magnesium deficiency hints at the possibility of root aphids. Has this been eliminated? They are a most common vector.
I've read through those links and thought it was mosaic virus but the deeper into forums and articles I get the more confusing it gets. What would you do w these plants 7 weeks into flower? Treat them or leave them to finish and then sterilize the whole room? I have some clones ready to go so I could treat them with RNA pro but would I ultimately be better off just scrapping everything and restarting with a clean sterile environment? I'm going to get a better microscope and check everywhere tonight for bugs.

Ouch, $200 for an 8oz bottle!
Shit I was hoping it wasn't bugs..
How do you treat them with this? A 1/4oz bottle be enough to foliar spray? I guess im screwed on this one at 7 weeks into flower but Ill try to get them in veg room. Could this be purchased local from a hydro shop ?
Yeah the 1/4 once will treat MANY times ! It's 8 DROPS per gallon mix rate !

You can look for Broad Mites all you want. They are VERY small at about the size of the diameter of a white fly leg. The actually burrow into the leaf stem veins.

Yawn. Here we go again....

http://en.m.wikipedia.org/wiki/Sunn-hemp_mosaic_virus

http://www.hempmosaicvirus.com

Plenty of images out there, search a little.
This shit again? Over the years I, and some others have had direct contact with Mich State Univ. Ag science on this problem. We have sent almost 200 samples to them testing for ANY mosaic virus (many of those with the discoloration depicted in many of the images). NONE have come back as poss. for Mosaic virus. In talking to profs and Grad students. We were told that any MV can ONLY be transferred by DIRECT CONTACT with an infected plant. That means that the plant must touch an infected plant or by you touching an infected plant then touching one not infected. Insect infection is more difficult, but possible. Careful indoor growers are the LEAST likely to get the problem.The Prof said that they have NOT seen a poss in cannabis for years and years. He feels this is due to there NOT being grown industrial hemp in this country as a crop after WW2. Furthermore he feels that the plant has gotten an strong resistance to it from all the cross breeding going on.
When asked about the Wiki post, he reminded me that Wiki is user posted material and subject to doubt!

He states this simple fact. "MV will spread through out the plant and in time express the "discoloration" in many area's faster then Broad mites. Has it spread? Is the plant truly suffering?"

100 % of the tests came back as Broad Mites!!!!!

Treat for Broad mites.

If you must believe in Sunn-Hemp........The solution is simple.......Don't touch other peoples plants and keep the garden area CLEAN and pest free !!!!!!!!!!!

Still get it? BROAD MITES!

I know who you are Snaps (not hard to have figured out due to some of your posts), I know what you do. I respect your opinions........With all due respect....
I feel your wrong on this one.

Looks more like a toxicity as opposed to a deficiency or insects to me.

Read the ROLS thread in the organics section.

You won't experience these problems ever again.

Take another look at the pics Bob,,,,,mottled discoloration,whirling leaf,,,,,,,Broad Mites !

Note: There ARE strains that will get that mottled "look" all over them, (The Doctor from GreenHouse is one) that do NOT get the leaf whirl !! This is a recessive a genetic trait common to that strain and should not be confused with Broad Mites.
