Q.many small holes in newly planted broccoli
After planting out broccoli I noticed that after five days that four of the plants’ leaves had many small holes in them. I removed the plants and inspected them but could find no sign of insects or any other visible signs of pests. I removed the damaged plants and replanted some extra undamaged broccoli, these appear to be good even after 1 week, however what would have been plant number five in the same row is now showing the same problem as in the first four plants, please see uploaded pictures.
