growing 13 of these in greenhouse - 2 plants recently developed a lot of minute white spots and one of these has minute green pimples on the underside of the leaf. These two plants are positioned at opposite ends of the greenhouse, one by the door and the other at the far end corner. Havent seen any fly and dont know what could cause this. All plants treated identically so at a loss to understand reason Remainder of plants look very healthy and have already cut a number of fruit from them.
any information welcome
