Thanks, that makes sense Roland, because Ink Spot seems to set in when the plants are waterd during warm periods at the end of growth. If they have got too dry and gone dormant in hot spring weather, wetting them brings Ink spot and other rots. I have found a more moisture retentive compost seems to prevent the premature dormancy and give a longer growing season.
