    Well hopefully not, I've taken a few measures but sure if problem resurfaces I will. Problem is viruses can look like a number of other things: nutrient deficiency ect. Seedlings tend to have banana shaped leaves, puckering and very slow growth. But two weeks into flowering the worst of them...

    A virus has got into my last 12 crops somehow, seems to be reinfecting despite total replacement of all equipment and scrupulous hygiene. I suspect it is in the fabric of the house and being dragged in by the extractor. any suggestions?
