I recently planted Astia zucchini from transplants I grew from seed. I have planted this variety in the past and had no problems. This year I notice that the leaves get yellow spots that seem to spread. * I do not see any sign of insect activity except for a very tiny spider. If you zoom in on the spider photo you should be able to see it. I do not see any sign of sticky stuff or aphids. * I use soaker hoses to water and water 2-3 times a week for 2 hours each time if it hasn't been raining. * The bed gets about 6 hours of full sun. *The transplants are planted in a bed that had broccoli lady year. Thanks! Janice
