Why vegetable plants are getting yellow in color & not bearing fruits

I've tried to grow vegetables in my backyard, but this year the results have been very disappointing (such as tomato, gourd plants). The plants are growing to a point where they flowering, but not bearing any fruits. The leaves are getting discolored (yellowish). Please see the attached pictures.
I'm pretty confident that its not due to under-watering as I've drip system running wherein these plants get adequate amount of water every alternate day.
Any ideas what could be causing this ? Really appreciate for responses.
Hi Ktr ch, Have you fed them? I was told if you only water and don't feed occasionally not only are they not getting extra but the water eventually leaches nutrients down into the soil out of reach of the roots. Maybe something like tomato food
The tomatoes don't look too bad although they are a bit small. I would remove any dead and yellowing leaves as they will do more harm than good if left. I suspect the fact that temperatures have been so up and down has put them back but there is still plenty of time left for them to set and ripen fruit.
As far as the gourd leaves go, they look like they are having the life sucked out of them by (I suspect) spider mites or possibly thrips. Try using a magnifying glass to inspect the underside of the leaves (spider mites are too small to see with the naked eye) and look for webbing at the tips of the vines. Spraying both the top and bottom of all of the leaves with SB plant invigorator may help if they are not too far gone. Insecticides are usually useless as spider mite is generally immune to them.
