2nd growing from tubers for me. The tubers was stored over winter before planting in the house in pots, then planting outside. Although I planted out, 2 weeks before the last possible frost date for my area, no frost happened.
Can anyone help with leave damage?
The first has patches on all leaves and stems. All 3 plants divided from the same tuber showing same syptoms. No other Dahlias do.

The second, a couple of plants have black patches on a few leaves, at the tips or sides only,
