zucchini fruit problem
I have a problem with hydroponic zucchini. The plants are doing excellent and are producing high quantities of fruits however the fruits are drying up after a week or two from forming I suspect calcium defeciency but I am not sure. You might be able to pin point the problem for me.

Based on the photos that you submitted, I think your issue is one of pollination. What are you using to help with pollination? Often in large operations in the United States, pollinators such as bees are used in greenhouses. If the flower is not pollinated, a fruit will still form. However, these fruit will tend to abort and not fully form.
