Wrapping up week five of flowering; all four plants are lush with bud and 24 inches tall. First noticed this on old growth, but now appearing on younger leaves, too. No visible insect pests. Affected leaves are dry and somewhat brittle. Tobacco mosaic perhaps? Concerned since I’m 3-4 weeks away from harvest. Diagnosis, treatment and prognosis, or am I SOL? Thanks!
