Answer 2

White spots are usually powdery mildew. It is not fatal but can get out of control if the weather is very warm and humid. You can try a fungicide if you want, but I'd prefer not to eat fungicide -tainted zucchini.

Zucchini are very susceptible to the dreaded squash vine borer and if your plants are looking weak and weedy, you might have it. Look at the top of the main stem just where it comes out of the ground. Does it look as if it is splitting or does it have a hole in it? If so, you probably have a vine borer grub in there. Get a sharp knife and carefully cut a slit from the hole or split along the stem, carefully prise open the stem and look inside. if you see a nasty gray-white grub about half an inch long, kill it and dig it out (this can get ugly). Check that there are no others. Now, carefully squeeze the stem back together again and mound dirt over it. The plant will probably survive and put down new roots where you buried the stem. You have to be careful when you do this not to break the stem completely, and the plant may be too far gone to recover. Good Luck.

Answer 3

The leaves might be turning yellow either because of too much sunlight or the water.  The water that you are using to water your plants may have too much salt in it. I would suggest using fridge water or water that has been purified.

white spots may indicate bug fungus. You should spray some anti-fungus spray (which you can find at your local gardening store) on your plant.

Hope i helped.

give them a feed of super phosphate, the white spot is the start of mildew and fungi disease, get a  solution of milk and water say10% and spray the leaves you may save your plants
