This virus is found in other plants but I never saw it in pot it infects the plant and causes the leaves to curl to the side anyone else have this shit or ideas on how to deal with it.
New one on me.....CurlingDisease....

this isn't my photo but this is what the leaves are doing on the worst of them. I sprayed one of them with a mix of olive leaf extract, elderberry extract, colloidal gold, pau d' arco, yucca extract and EZ wet, it burnt the edges a little on the old growth but the new growth looks normal. I watered in EM microbes too so we will see.

Viruses
Viruses rarely kill Cannabis. They only exist and replicate in living plants. Viruses can, however, seriously reduce yields. Once acquired, they are nearly impossible to eradicate. Viruses invade all parts of plants. Pollen and seed infections transmit viruses to subsequent generations.
Five viral syndromes are described in the literature. In addition to these naturally-occurring infections, Hartowicz et al. (1971) screened 22 common plant viruses for their ability to infect wild hemp. Over half the viruses could infect Cannabis.
The hemp streak virus (HSV) is frequently cited on fiber cultivars in Europe. Foliar symptoms begin as a pale green chlorosis. Chlorotic areas soon develop into a series of interveinal yellow streaks or chevron-stripes. Some-times brown necrotic flecks appear, each fleck surrounded by a pale green halo. Flecks appear along the margins and tips of older leaves and often coalesce. Streak symptoms predominate in moist weather, flecks appear during dry weather. Leaf margins become wrinkled and leaf tips roll upward, leaflets curl into spirals. Whole plants assume a "wavy wilt" appearance.
The hemp mozaic virus has been described on fiber cultivars in Europe and drug cultivars in Pakistan. Symptoms were described as a gray leaf mosaics. Three other viruses have been cited on European hemp—the alfalfa mozaic virus (=lucerne mozaic virus), cucumber mozaic virus, and the arabis mozaic virus. Many insects transmit these viruses as they feed from plant to plant. According to Ceapoiu (195
, the worst vectors of Cannabis viruses are bhang aphids (Phorodon cannabis), greenhouse whiteflies (Trialeudodes vaporariorum), onion thrips (Thrips tabaci) and green peach aphids (Myzus persicae).
