here I am again with more problems

My hybrid bush cucumbers were doing super great I've had like 6 already big green and beautiful. Now they don't turn green they turn yellow. And the new ones that are growing are growing slow and only getting plump at the stem end and the other outter end stays all pointy and skinny. O and I also have leaf miners attacking this plant too

, if that matters. The one that is super yellow started off light green and I left it hoping it would get a little greener and its lemon yellow now. . .help
