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.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.
