Hi all, been lurking for a long time but this is my first post. Wish it were under better circumstances. First a little background. I have been growing for 15 years and have been a smoker the entire time. Usually smoke in the rooms as they are the only part of my residences that were for me alone. Never had a problem. Recently I had an issue with spider mites. Tried several home made and commercial sprays before discovering no pest strips which eliminated them. The last spray I tried was a nicotene formula. One of the sites I referred to didn't mention boiling at all and another mentioned that it was an optional step to prevent tobacco mosaic virus which probably cannot be spread to mj anyway. I have since read otherwise. I heated the water to boiling then removed from heat and soaked tobacco from butts wrapped in a paper towel. Sprayed everything, mothers, clones and some that just started flowering. It worked about as well as any of the other sprays, meaning it knocked them down but was not effective for eradication. Now I have some weird looking leaf patterns and it appears to be affecting all of the plants. They have been looking consistently rough because of all the recent spraying (neem, alcohol, soaps, etc.) but I have not sprayed in several days and it appears to be spreading. I do not believe it is a nutrient or PH issue as there are three different sets of plants which receive three different formulas which have been successful for me in the past. But it is possible since this is a new location and variations in tap water quality could be causing lockout. Does anyone have experience with TMV? Is it generally fatal or will the plants limp along looking and yielding like crap? I have searched the web and cannot find any pics of mj with this virus. I have pics from three different plants showing what appears to be the same problem. The patterns appeared on two of them just over the past night. Any help would be appreciated since the sooner I know for sure whether it is this virus or not, I can take appropriate steps such as shutting down, sterilizing, and getting new clone or seed stock. Thanks in advance.
